By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users.  We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors.  You can apply it to +your programs, too. + +  When we speak of free software, we are referring to freedom, not +price.  Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + +  To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights.  Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + +  For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received.  You must make sure that they, too, receive +or can get the source code.  And you must show them these terms so they +know their rights. + +  Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + +  For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software.  For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + +  Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so.  This is fundamentally incompatible with the aim of +protecting users' freedom to change the software.  The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable.  Therefore, we +have designed this version of the GPL to prohibit the practice for those +products.  If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + +  Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary.  To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + +  The precise terms and conditions for copying, distribution and +modification follow. + +                       TERMS AND CONDITIONS + +  0. Definitions. + +  "This License" refers to version 3 of the GNU General Public License. + +  "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + +  "The Program" refers to any copyrightable work licensed under this +License.  Each licensee is addressed as "you".  "Licensees" and +"recipients" may be individuals or organizations. + +  To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy.  The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + +  A "covered work" means either the unmodified Program or a work based +on the Program. + +  To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy.  Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + +  To "convey" a work means any kind of propagation that enables other +parties to make or receive copies.  Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + +  An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License.  If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + +  1. Source Code. + +  The "source code" for a work means the preferred form of the work +for making modifications to it.  "Object code" means any non-source +form of a work. + +  A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + +  The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form.  A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + +  The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities.  However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work.  For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + +  The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + +  The Corresponding Source for a work in source code form is that +same work. + +  2. Basic Permissions. + +  All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met.  This License explicitly affirms your unlimited +permission to run the unmodified Program.  The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work.  This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + +  You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force.  You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright.  Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + +  Conveying under any other circumstances is permitted solely under +the conditions stated below.  Sublicensing is not allowed; section 10 +makes it unnecessary. + +  3. Protecting Users' Legal Rights From Anti-Circumvention Law. + +  No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + +  When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + +  4. Conveying Verbatim Copies. + +  You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + +  You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + +  5. Conveying Modified Source Versions. + +  You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + +    a) The work must carry prominent notices stating that you modified +    it, and giving a relevant date. + +    b) The work must carry prominent notices stating that it is +    released under this License and any conditions added under section +    7.  This requirement modifies the requirement in section 4 to +    "keep intact all notices". + +    c) You must license the entire work, as a whole, under this +    License to anyone who comes into possession of a copy.  This +    License will therefore apply, along with any applicable section 7 +    additional terms, to the whole of the work, and all its parts, +    regardless of how they are packaged.  This License gives no +    permission to license the work in any other way, but it does not +    invalidate such permission if you have separately received it. + +    d) If the work has interactive user interfaces, each must display +    Appropriate Legal Notices; however, if the Program has interactive +    interfaces that do not display Appropriate Legal Notices, your +    work need not make them do so. + +  A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit.  Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + +  6. Conveying Non-Source Forms. + +  You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + +    a) Convey the object code in, or embodied in, a physical product +    (including a physical distribution medium), accompanied by the +    Corresponding Source fixed on a durable physical medium +    customarily used for software interchange. + +    b) Convey the object code in, or embodied in, a physical product +    (including a physical distribution medium), accompanied by a +    written offer, valid for at least three years and valid for as +    long as you offer spare parts or customer support for that product +    model, to give anyone who possesses the object code either (1) a +    copy of the Corresponding Source for all the software in the +    product that is covered by this License, on a durable physical +    medium customarily used for software interchange, for a price no +    more than your reasonable cost of physically performing this +    conveying of source, or (2) access to copy the +    Corresponding Source from a network server at no charge. + +    c) Convey individual copies of the object code with a copy of the +    written offer to provide the Corresponding Source.  This +    alternative is allowed only occasionally and noncommercially, and +    only if you received the object code with such an offer, in accord +    with subsection 6b. + +    d) Convey the object code by offering access from a designated +    place (gratis or for a charge), and offer equivalent access to the +    Corresponding Source in the same way through the same place at no +    further charge.  You need not require recipients to copy the +    Corresponding Source along with the object code.  If the place to +    copy the object code is a network server, the Corresponding Source +    may be on a different server (operated by you or a third party) +    that supports equivalent copying facilities, provided you maintain +    clear directions next to the object code saying where to find the +    Corresponding Source.  Regardless of what server hosts the +    Corresponding Source, you remain obligated to ensure that it is +    available for as long as needed to satisfy these requirements. + +    e) Convey the object code using peer-to-peer transmission, provided +    you inform other peers where the object code and Corresponding +    Source of the work are being offered to the general public at no +    charge under subsection 6d. + +  A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + +  A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling.  In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage.  For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product.  A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + +  "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source.  The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + +  If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information.  But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + +  The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed.  Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + +  Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + +  7. Additional Terms. + +  "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law.  If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + +  When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it.  (Additional permissions may be written to require their own +removal in certain cases when you modify the work.)  You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + +  Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + +    a) Disclaiming warranty or limiting liability differently from the +    terms of sections 15 and 16 of this License; or + +    b) Requiring preservation of specified reasonable legal notices or +    author attributions in that material or in the Appropriate Legal +    Notices displayed by works containing it; or + +    c) Prohibiting misrepresentation of the origin of that material, or +    requiring that modified versions of such material be marked in +    reasonable ways as different from the original version; or + +    d) Limiting the use for publicity purposes of names of licensors or +    authors of the material; or + +    e) Declining to grant rights under trademark law for use of some +    trade names, trademarks, or service marks; or + +    f) Requiring indemnification of licensors and authors of that +    material by anyone who conveys the material (or modified versions of +    it) with contractual assumptions of liability to the recipient, for +    any liability that these contractual assumptions directly impose on +    those licensors and authors. + +  All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10.  If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term.  If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + +  If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + +  Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + +  8. Termination. + +  You may not propagate or modify a covered work except as expressly +provided under this License.  Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + +  However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + +  Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + +  Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License.  If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + +  9. Acceptance Not Required for Having Copies. + +  You are not required to accept this License in order to receive or +run a copy of the Program.  Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance.  However, +nothing other than this License grants you permission to propagate or +modify any covered work.  These actions infringe copyright if you do +not accept this License.  Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + +  10. Automatic Licensing of Downstream Recipients. + +  Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License.  You are not responsible +for enforcing compliance by third parties with this License. + +  An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations.  If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + +  You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License.  For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + +  11. Patents. + +  A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based.  The +work thus licensed is called the contributor's "contributor version". + +  A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version.  For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + +  Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + +  In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement).  To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + +  If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients.  "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + +  If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + +  A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License.  You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + +  Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + +  12. No Surrender of Others' Freedom. + +  If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License.  If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all.  For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + +  13. Use with the GNU Affero General Public License. + +  Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work.  The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + +  14. Revised Versions of this License. + +  The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time.  Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +  Each version is given a distinguishing version number.  If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation.  If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + +  If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + +  Later license versions may give you additional or different +permissions.  However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + +  15. Disclaimer of Warranty. + +  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE.

All CSS +is compatible with LESS, so you can start using new features with your existing CSS. + +It is designed to be compatible with [less.js](http://lesscss.org), and suitable +as a drop in replacement for PHP projects. + +## Getting Started + +The homepage for **lessphp** can be found at [http://leafo.net/lessphp/][1]. + +You can follow development at the project's [GitHub][2]. + +Including **lessphp** in your project is as simple as dropping the single +include file into your code base and running the appropriate compile method as +described in the [PHP Interface](#php_interface). + +  [1]: http://leafo.net/lessphp "lessphp homepage" +  [2]: https://github.com/leafo/lessphp "lessphp GitHub page" + +## Installation + +**lessphp** is distributed entirely in a single stand-alone file. Download the +latest version from either [the homepage][1] or [GitHub][2]. + +Development versions can also be downloading from GitHub. + +Place `lessphp.inc.php` in a location available to your PHP scripts, and +include it. That's it! you're ready to begin. + +## The Language + +**lessphp** is very easy to learn because it generally functions how you would +expect it to. If you feel something is challenging or missing, feel free to +open an issue on the [bug tracker](https://github.com/leafo/lessphp/issues). + +It is also easy to learn because any standards-compliant CSS code is valid LESS +code. You are free to gradually enhance your existing CSS code base with LESS +features without having to worry about rewriting anything. + +The following is a description of the new languages features provided by LESS. + +### Line Comments + +Simple but very useful; line comments are started with `//`: + +    ```less +    // this is a comment +    body { +      color: red; // as is this +      /* block comments still work also */ +    } +    ``` + +### Variables +Variables are identified with a name that starts with `@`. To declare a +variable, you create an appropriately named CSS property and assign it a value: + +    ```less +    @family: "verdana"; +    @color: red; +    body { +      @mycolor: red; +      font-family: @family; +      color: @color; +      border-bottom: 1px solid @color; +    } +    ``` + +Variable declarations will not appear in the output. Variables can be declared +in the outer most scope of the file, or anywhere else a CSS property may +appear. They can hold any CSS property value. + +Variables are only visible for use from their current scope, or any enclosed +scopes. + +If you have a string or keyword in a variable, you can reference another +variable by that name by repeating the `@`: + +    ```less +    @value: 20px; +    @value_name: "value"; + +    width: @@value_name; +    ``` + +### Expressions + +Expressions let you combine values and variables in meaningful ways. For +example you can add to a color to make it a different shade. Or divide up the +width of your layout logically. You can even concatenate strings. + +Use the mathematical operators to evaluate an expression: + +    ```less +    @width: 960px; +    .nav { +      width: @width / 3; +      color: #001 + #abc; +    } +    .body { +      width: 2 * @width / 3; +      font-family: "hel" + "vetica"; +    } +    ``` + +Parentheses can be used to control the order of evaluation. They can also be +used to force an evaluation for cases where CSS's syntax makes the expression +ambiguous. + +The following property will produce two numbers, instead of doing the +subtraction: + +    ```less +    margin: 10px -5px; +    ``` + +To force the subtraction: + +    ```less +    margin: (10px -5px); +    ``` + +It is also safe to surround mathematical operators by spaces to ensure that +they are evaluated: + +    ```less +    margin: 10px - 5px; +    ``` + +Division has a special quirk. There are certain CSS properties that use the `/` +operator as part of their value's syntax. Namely, the [font][4] shorthand and +[border-radius][3]. + +  [3]: https://developer.mozilla.org/en/CSS/border-radius +  [4]: https://developer.mozilla.org/en/CSS/font + + +Thus, **lessphp** will ignore any division in these properties unless it is +wrapped in parentheses. For example, no division will take place here: + +    ```less +    .font { +      font: 20px/80px "Times New Roman"; +    } +    ``` + +In order to force division we must wrap the expression in parentheses: + +    ```less +    .font { +      font: (20px/80px) "Times New Roman"; +    } +    ``` + +If you want to write a literal `/` expression without dividing in another +property (or a variable), you can use [string unquoting](#string_unquoting): + +    ```less +    .var { +      @size: ~"20px/80px"; +      font: @size sans-serif; +    } +    ``` + +### Nested Blocks + +By nesting blocks we can build up a chain of CSS selectors through scope +instead of repeating them. In addition to reducing repetition, this also helps +logically organize the structure of our CSS. + +    ```less +    ol.list { +      li.special { +        border: 1px solid red; +      } + +      li.plain { +        font-weight: bold; +      } +    } +    ``` + + +This will produce two blocks, a `ol.list li.special` and `ol.list li.plain`. + +Blocks can be nested as deep as required in order to build a hierarchy of +relationships. + +The `&` operator can be used in a selector to represent its parent's selector. +If the `&` operator is used, then the default action of appending the parent to +the front of the child selector separated by space is not performed. + +    ```less +    b { +      a & { +        color: red; +      } + +      // the following have the same effect + +      & i { +        color: blue; +      } + +      i { +        color: blue; +      } +    } +    ``` + + +Because the `&` operator respects the whitespace around it, we can use it to +control how the child blocks are joined. Consider the differences between the +following: + +    ```less +    div { +      .child-class { color: purple; } + +      &.isa-class { color: green; } + +      #child-id { height: 200px; } + +      &#div-id { height: 400px; } + +      &:hover { color: red; } + +      :link { color: blue; } +    } +    ``` + +The `&` operator also works with [mixins](#mixins), which produces interesting results: + +    ```less +    .within_box_style() { +      .box & { +        color: blue; +      } +    } + +    #menu { +      .within_box_style; +    } +    ``` + +### Mixins + +Any block can be mixed in just by naming it: + +    ```less +    .mymixin { +      color: blue; +      border: 1px solid red; + +      .special { +        font-weight: bold; +      } +    } + + +    h1 { +      font-size: 200px; +      .mixin; +    } +    ``` + +All properties and child blocks are mixed in. + +Mixins can be made parametric, meaning they can take arguments, in order to +enhance their utility. A parametric mixin all by itself is not outputted when +compiled. Its properties will only appear when mixed into another block. + +The canonical example is to create a rounded corners mixin that works across +browsers: + +    ```less +    .rounded-corners(@radius: 5px) { +      border-radius: @radius; +      -webkit-border-radius: @radius; +      -moz-border-radius: @radius; +    } + +    .header { +      .rounded-corners(); +    } + +    .info { +      background: red; +      .rounded-corners(14px); +    } +    ``` + +If you have a mixin that doesn't have any arguments, but you don't want it to +show up in the output, give it a blank argument list: + +    ```less +    .secret() { +      font-size: 6000px; +    } + +    .div { +      .secret; +    } +    ``` + +If the mixin doesn't need any arguments, you can leave off the parentheses when +mixing it in, as seen above. + +You can also mixin a block that is nested inside other blocks. You can think of +the outer block as a way of making a scope for your mixins. You just list the +names of the mixins separated by spaces, which describes the path to the mixin +you want to include. Optionally you can separate them by `>`. + +    ```less +    .my_scope  { +      .some_color { +        color: red; +        .inner_block { +          text-decoration: underline; +        } +      } +      .bold { +        font-weight: bold; +        color: blue; +      } +    } + +    .a_block { +      .my_scope .some_color; +      .my_scope .some_color .inner_block; +    } + +    .another_block { +      // the alternative syntax +      .my_scope > .bold; +    } +    ``` + +#### `@arguments` Variable + +Within an mixin there is a special variable named `@arguments` that contains +all the arguments passed to the mixin along with any remaining arguments that +have default values. The value of the variable has all the values separated by +spaces. + +This useful for quickly assigning all the arguments: + +    ```less +    .box-shadow(@x, @y, @blur, @color) { +      box-shadow: @arguments; +      -webkit-box-shadow: @arguments; +      -moz-box-shadow: @arguments; +    } +    .menu { +      .box-shadow(1px, 1px, 5px, #aaa); +    } +    ``` + +In addition to the arguments passed to the mixin, `@arguments` will also include +remaining default values assigned by the mixin: + + +    ```less +    .border-mixin(@width, @style: solid, @color: black) { +      border: @arguments; +    } + +    pre { +      .border-mixin(4px, dotted); +    } + +    ``` + + +#### Pattern Matching + +When you *mix in* a mixin, all the available mixins of that name in the current +scope are checked to see if they match based on what was passed to the mixin +and how it was declared. + +The simplest case is matching by number of arguments. Only the mixins that +match the number of arguments passed in are used. + +    ```less +    .simple() { // matches no arguments +      height: 10px; +    } + +    .simple(@a, @b) { // matches two arguments +      color: red; +    } + +    .simple(@a) { // matches one argument +      color: blue; +    } + +    div { +      .simple(10); +    } + +    span { +      .simple(10, 20); +    } +    ``` + +Whether an argument has default values is also taken into account when matching +based on number of arguments: + +    ```less +    // matches one or two arguments +    .hello(@a, @b: blue) { +      height: @a; +      color: @b; +    } + +    .hello(@a, @b) { // matches only two +      width: @a; +      border-color: @b; +    } + +    .hello(@a) { // matches only one +      padding: 1em; +    } + +    div { +      .hello(10px); +    } + +    pre { +      .hello(10px, yellow); +    } +    ``` + +Additionally, a *vararg* value can be used to further control how things are +matched.  A mixin's argument list can optionally end in the special argument +named `...`.  The `...` may match any number of arguments, including 0. + +    ```less +    // this will match any number of arguments +    .first(...) { +      color: blue; +    } + +    // matches at least 1 argument +    .second(@arg, ...) { +      height: 200px + @arg; +    } + +    div { .first("some", "args"); } +    pre { .second(10px); } +    ``` + +If you want to capture the values that get captured by the *vararg* you can +give it a variable name by putting it directly before the `...`. This variable +must be the last argument defined. It's value is just like the special +[`@arguments` variable](#arguments_variable), a space separated list. + + +    ```less +    .hello(@first, @rest...) { +      color: @first; +      text-shadow: @rest; +    } + +    span { +      .hello(red, 1px, 1px, 0px, white); +    } + +    ``` + +Another way of controlling whether a mixin matches is by specifying a value in +place of an argument name when declaring the mixin: + +    ```less +    .style(old, @size) { +      font: @size serif; +    } + +    .style(new, @size) { +      font: @size sans-serif; +    } + +    .style(@_, @size) { +      letter-spacing: floor(@size / 6px); +    } + +    em { +      @switch: old; +      .style(@switch, 15px); +    } +    ``` + +Notice that two of the three mixins were matched. The mixin with a matching +first argument, and the generic mixin that matches two arguments. It's common +to use `@_` as the name of a variable we intend to not use. It has no special +meaning to LESS, just to the reader of the code. + +#### Guards + +Another way of restricting when a mixin is mixed in is by using guards. A guard +is a special expression that is associated with a mixin declaration that is +evaluated during the mixin process. It must evaluate to true before the mixin +can be used. + +We use the `when` keyword to begin describing a list of guard expressions. + +Here's a simple example: + +    ```less +    .guarded(@arg) when (@arg = hello) { +      color: blue; +    } + +    div { +      .guarded(hello); // match +    } + +    span { +      .guarded(world); // no match +    } +    ``` +Only the `div`'s mixin will match in this case, because the guard expression +requires that `@arg` is equal to `hello`. + +We can include many different guard expressions by separating them by commas. +Only one of them needs to match to trigger the mixin: + +    ```less +    .x(@a, @b) when (@a = hello), (@b = world) { +      width: 960px; +    } + +    div { +      .x(hello, bar); // match +    } + +    span { +      .x(foo, world); // match +    } + +    pre { +      .x(foo, bar); // no match +    } +    ``` + +Instead of a comma, we can use `and` keyword to make it so all of the guards +must match in order to trigger the mixin. `and` has higher precedence than the +comma. + +    ```less +    .y(@a, @b) when (@a = hello) and (@b = world) { +      height: 600px; +    } + +    div { +      .y(hello, world); // match +    } + +    span { +      .y(hello, bar); // no match +    } +    ``` + +Commas and `and`s can be mixed and matched. + +You can also negate a guard expression by using `not` in from of the parentheses: + +    ```less +    .x(@a) when not (@a = hello) { +      color: blue; +    } + +    div { +      .x(hello); // no match +    } +    ``` + +The `=` operator is used to check equality between any two values. For numbers +the following comparison operators are also defined: + +`<`, `>`, `=<`, `>=` + +There is also a collection of predicate functions that can be used to test the +type of a value. + +These are `isnumber`, `iscolor`, `iskeyword`, `isstring`, `ispixel`, +`ispercentage` and `isem`. + +    ```less +    .mix(@a) when (ispercentage(@a)) { +      height: 500px * @a; +    } +    .mix(@a) when (ispixel(@a)) { +      height: @a; +    } + +    div.a { +      .mix(50%); +    } + +    div.a { +      .mix(350px); +    } +    ``` + +#### !important + +If you want to apply the `!important` suffix to every property when mixing in a +mixin, just append `!important` to the end of the call to the mixin: + +    ```less +    .make_bright { +      color: red; +      font-weight: bold; +    } + +    .color { +      color: green; +    } + +    body { +      .make_bright() !important; +      .color(); +    } + +    ``` + +### Selector Expressions + +Sometimes we want to dynamically generate the selector of a block based on some +variable or expression. We can do this by using *selector expressions*. Selector +expressions are CSS selectors that are evaluated in the current scope before +being written out. + +A simple example is a mixin that dynamically creates a selector named after the +mixin's argument: + +    ```less +    .create-selector(@name) { +      (e(@name)) { +        color: red; +      } +    } + +    .create-selector("hello"); +    .create-selector("world"); +    ``` + +Any selector that is enclosed in `()` will have it's contents evaluated and +directly written to output. The value is not changed any way before being +outputted, thats why we use the `e` function. If you're not familiar, the `e` +function strips quotes off a string value. If we didn't have it, then the +selector would have quotes around it, and that's not valid CSS! + +Any value can be used in a selector expression, but it works best when using +strings and things like [String Interpolation](#string_interpolation). + +Here's an interesting example adapted from Twitter Bootstrap. A couple advanced +things are going on. We are using [Guards](#guards) along with a recursive +mixin to work like a loop to generate a series of CSS blocks. + + +    ```less +    // create our recursive mixin: +    .spanX (@index) when (@index > 0) { +      (~".span@{index}") { +        width: @index * 100px; +      } +      .spanX(@index - 1); +    } +    .spanX (0) {} + +    // mix it into the global scopee: +    .spanX(4); +    ``` + +### Import + +Multiple LESS files can be compiled into a single CSS file by using the +`@import` statement. Be careful, the LESS import statement shares syntax with +the CSS import statement. If the file being imported ends in a `.less` +extension, or no extension, then it is treated as a LESS import. Otherwise it +is left alone and outputted directly: + +    ```less +    // my_file.less +    .some-mixin(@height) { +      height: @height; +    } + +    // main.less +    @import "main.less" // will import the file if it can be found +    @import "main.css" // will be left alone + +    body { +      .some-mixin(400px); +    } +    ``` + +All of the following lines are valid ways to import the same file: + +    ```less +    @import "file"; +    @import 'file.less'; +    @import url("file"); +    @import url('file'); +    @import url(file); +    ``` + +When importing, the `importDir` is searched for files. This can be configured, +see [PHP Interface](#php_interface). + +### String Interpolation + +String interpolation is a convenient way to insert the value of a variable +right into a string literal. Given some variable named `@var_name`, you just +need to write it as `@{var_name}` from within the string to have its value +inserted: + +    ```less +    @symbol: ">"; +    h1:before { +      content: "@{symbol}: "; +    } + +    h2:before { +      content: "@{symbol}@{symbol}: "; +    } +    ``` + +There are two kinds of strings, implicit and explicit strings. Explicit strings +are wrapped by double quotes, `"hello I am a string"`, or single quotes `'I am +another string'`. Implicit strings only appear when using `url()`. The text +between the parentheses is considered a string and thus string interpolation is +possible: + +    ```less +    @path: "files/"; +    body { +      background: url(@{path}my_background.png); +    } +    ``` + +### String Format Function + +The `%` function can be used to insert values into strings using a *format +string*. It works similar to `printf` seen in other languages. It has the +same purpose as string interpolation above, but gives explicit control over +the output format. + +    ```less +    @symbol: ">"; +    h1:before { +      content: %("%s: ", @symbol); +    } +    ``` + +The `%` function takes as its first argument the format string, following any +number of addition arguments that are inserted in place of the format +directives. + +A format directive starts with a `%` and is followed by a single character that +is either `a`, `d`, or `s`: + +    ```less +    strings: %("%a %d %s %a", hi, 1, 'ok', 'cool'); +    ``` + +`%a` and `%d` format the value the same way: they compile the argument to its +CSS value and insert it directly. When used with a string, the quotes are +included in the output. This typically isn't what we want, so we have the `%s` +format directive which strips quotes from strings before inserting them. + +The `%d` directive functions the same as `%a`, but is typically used for numbers +assuming the output format of numbers might change in the future. + +### String Unquoting + +Sometimes you will need to write proprietary CSS syntax that is unable to be +parsed. As a workaround you can place the code into a string and unquote it. +Unquoting is the process of outputting a string without its surrounding quotes. +There are two ways to unquote a string. + +The `~` operator in front of a string will unquote that string: + +    ```less +    .class { +      // a made up, but problematic vendor specific CSS +      filter: ~"Microsoft.AlphaImage(src='image.png')"; +    } +    ``` + +If you are working with other types, such as variables, there is a built in +function that let's you unquote any value. It is called `e`. + +    ```less +    @color: "red"; +    .class { +      color: e(@color); +    } +    ``` + +### Built In Functions + +**lessphp** has a collection of built in functions: + +* `e(str)` -- returns a string without the surrounding quotes. +  See [String Unquoting](#string_unquoting) + +* `floor(number)` -- returns the floor of a numerical input +* `round(number)` -- returns the rounded value of numerical input + +* `lighten(color, percent)` -- lightens `color` by `percent` and returns it +* `darken(color, percent)` -- darkens `color` by `percent` and returns it + +* `saturate(color, percent)` -- saturates `color` by `percent` and returns it +* `desaturate(color, percent)` -- desaturates `color` by `percent` and returns it + +* `fadein(color, percent)` -- makes `color` less transparent by `percent` and returns it +* `fadeout(color, percent)` -- makes `color` more transparent by `percent` and returns it + +* `spin(color, amount)` -- returns a color with `amount` degrees added to hue + +* `fade(color, amount)` -- returns a color with the alpha set to `amount` + +* `hue(color)` -- returns the hue of `color` + +* `saturation(color)` -- returns the saturation of `color` + +* `lightness(color)` -- returns the lightness of `color` + +* `alpha(color)` -- returns the alpha value of `color` or 1.0 if it doesn't have an alpha + +* `percentage(number)` -- converts a floating point number to a percentage, e.g. `0.65` -> `65%` + +* `mix(color1, color1, percent)` -- mixes two colors by percentage where 100% +  keeps all of `color1`, and 0% keeps all of `color2`. Will take into account +  the alpha of the colors if it exists. See +  <http://sass-lang.com/docs/yardoc/Sass/Script/Functions.html#mix-instance_method>. + +* `rgbahex(color)` -- returns a string containing 4 part hex color. + +   This is used to convert a CSS color into the hex format that IE's filter +   method expects when working with an alpha component. + +       ```less +       .class { +          @start: rgbahex(rgba(25, 34, 23, .5)); +          @end: rgbahex(rgba(85, 74, 103, .6)); +          // abridged example +          -ms-filter: +            e("gradient(start=@{start},end=@{end})"); +       } +       ``` + +## PHP Interface + +The PHP interface lets you control the compiler from your PHP scripts. There is +only one file to include to get access to everything: + +    ```php +    <?php +    include "lessc.inc.php"; +    ``` + +To compile a file to a string (of CSS code): + +    ```php +    $less = new lessc("myfile.less"); +    $css = $less->parse(); +    ``` + +To compile a string to a string: + +    ```php +    $less = new lessc(); // a blank lessc +    $css = $less->parse("body { a { color: red } }"); +    ``` + +### Output Formatting + +Besides the default output formatter, **lessphp** comes with two additional +ones, and it's easy to make your own. + +The first extra formatter is called `compressed`. It compresses the output by +removing any extra whitespace. + +We use the `setFormatter` method set the formatter that should be used. Just +pass the name of the formatter: + +    ```php +    $less = new lessc("myfile.less"); + +    $less->setFormatter("compressed"); + +    $css = $less->parse(); +    ``` + +The second formatter is called `indent`. It will indent CSS blocks based on how +they were nested in the LESS code. + +#### Custom Formatter + +The easiest way to customize is to create your own instance of the formatter +and alter its public properties before passing it off to **lessphp**. The +`setFormatter` method can also take an instance of a formatter. + +For example, let's use tabs instead of the default two spaces to indent: + +    ```php +    $formatter = new lessc_formatter; +    $formatter->indentChar = "\t"; + +    $less = new lessc("myfile.less"); +    $less->setFormatter($formatter); +    $css = $less->parse(); +    ``` + +For more information about what can be configured with the formatter consult +the sourcecode. + +### Compiling Automatically + +Often, you want to write the compiled CSS to a file, and only recompile when +the original LESS file has changed. The following function will check if the +modification date of the LESS file is more recent than the CSS file.  The LESS +file will be compiled if it is. If the CSS file doesn't exist yet, then it will +also compile the LESS file. + +    ```php +    lessc::ccompile('myfile.less', 'mystyle.css'); +    ``` + +`ccompile` is very basic, it only checks if the input file's modification time. +It is not of any files that are brought in using `@import`. + +For this reason we also have `lessc::cexecute`. It functions slightly +differently, but gives us the ability to check changes to all files used during +the compile. It takes one argument, either the name of the file we want to +compile, or an existing *cache object*. Its return value is an updated cache +object. + +If we don't have a cache object, then we call the function with the name of the +file to get the initial cache object. If we do have a cache object, then we +call the function with it. In both cases, an updated cache object is returned. + +The cache object keeps track of all the files that must be checked in order to +determine if a rebuild is required. + +The cache object is a plain PHP `array`. It stores the last time it compiled in +`$cache['updated']` and output of the compile in `$cache['compiled']`. + +Here we demonstrate creating an new cache object, then using it to see if we +have a recompiled version available to be written: + + +    ```php +    $less_file = 'myfile.less'; +    $css_file = 'myfile.css'; + +    // create a new cache object, and compile +    $cache = lessc::cexecute('myfile.less'); +    file_put_contents($css_file, $cache['compiled']); + +    // the next time we run, write only if it has updated +    $last_updated = $cache['updated']; +    $cache = lessc::cexecute($cache); +    if ($cache['updated'] > $last_updated) { +        file_put_contents($css_file, $cache['compiled']); +    } + +    ``` + +In order for the system to fully work, we must save cache object between +requests. Because it's a plain PHP `array`, it's sufficient to +[`serialize`](http://php.net/serialize) it and save it the string somewhere +like a file or in persistent memory. + +An example with saving cache object to a file: + +    ```php +    function auto_compile_less($less_fname, $css_fname) { +      // load the cache +      $cache_fname = $less_fname.".cache"; +      if (file_exists($cache_fname)) { +        $cache = unserialize(file_get_contents($cache_fname)); +      } else { +        $cache = $less_fname; +      } + +      $new_cache = lessc::cexecute($cache); +      if (!is_array($cache) || $new_cache['updated'] > $cache['updated']) { +        file_put_contents($cache_fname, serialize($new_cache)); +        file_put_contents($css_fname, $new_cache['compiled']); +      } +    } + +    auto_compile_less('myfile.less', 'myfile.css'); +    ``` + +`lessc:cexecute` takes an optional second argument, `$force`. Passing in true +will cause the input to always be recompiled. + +### Error Handling + +All of the following methods will throw an `Exception` if the parsing fails: + +    ```php +    $less = new lessc(); +    try { +        $less->parse("} invalid LESS }}}"); +    } catch (Exception $ex) { +        echo "lessphp fatal error: ".$ex->getMessage(); +    } +    ``` +### Setting Variables From PHP + +The `parse` function takes a second optional argument. If you want to +initialize variables from outside the LESS file then you can pass in an +associative array of names and values. The values will parsed as CSS values: + +    ```php +    $less = new lessc(); +    echo $less->parse(".magic { color: @color;  width: @base - 200; }", +        array( +            'color' => 'red'; +            'base' => '960px'; +        )); +    ``` + +You can also do this when loading from a file. If the first argument of `parse` +is an array it will be used an array of variables to set. + +    ```php +    $less = new lessc("myfile.less"); +    echo $less->parse(array('color' => 'blue')); +    ``` + +### Custom Functions + +**lessphp** has a simple extension interface where you can implement user +functions that will be exposed in LESS code during the compile. They can be a +little tricky though because you need to work with the  **lessphp** type system. + +An instance of `lessc`, the **lessphp** compiler has two relevant methods: +`registerFunction` and `unregisterFunction`. `registerFunction` takes two +arguments, a name and a callable value. `unregisterFunction` just takes the +name of an existing function to remove. + +Here's an example that adds a function called `double` that doubles any numeric +argument: + +    ```php +    <?php +    include "lessc.inc.php"; + +    function lessphp_double($arg) { +        list($type, $value) = $arg; +        return array($type, $value*2); +    } + +    $myless = new myless(); +    $myless->registerFunction("double", "lessphp_double"); + +    // gives us a width of 800px +    echo $myless->parse("div { width: double(400px); }"); +    ``` + +The second argument to `registerFunction` is any *callable value* that is +understood by [`call_user_func`](http://php.net/call_user_func). + +If we are using PHP 5.3 or above then we are free to pass a function literal +like so: + +    ```php +    $myless->registerFunction("double", function($arg) { +        list($type, $value) = $arg; +        return array($type, $value*2); +    }); +    ``` + +Now let's talk about the `double` function itself. + +Although a little verbose, the implementation gives us some insight on the type +system. All values in **lessphp** are stored in an array where the 0th element +is a string representing the type, and the other elements make up the +associated data for that value. + +The best way to get an understanding of the system is to register is dummy +function which does a `vardump` on the argument. Try passing the function +different values from LESS and see what the results are. + +The return value of the registered function must also be a **lessphp** type, but if it is +a string or numeric value, it will automatically be coerced into an appropriate +typed value. In our example, we reconstruct the value with our modifications +while making sure that we preserve the original type. + +In addition to the arguments passed from **lessphp**, the instance of +**lessphp** itself is sent to the registered function as the second argument. + +## Command Line Interface + +**lessphp** comes with a command line script written in PHP that can be used to +invoke the compiler from the terminal. On Linux an OSX, all you need to do is +place `plessc` and `lessc.inc.php` somewhere in your PATH (or you can run it in +the current directory as well). On windows you'll need a copy of `php.exe` to +run the file. To compile a file, `input.less` to CSS, run: + +    ```bash +    $ plessc input.less +    ``` + +To write to a file, redirect standard out: + +    ```bash +    $ plessc input.less > output.css +    ``` + +To compile code directly on the command line: + +    ```bash +    $ plessc -r "@color: red; body { color: @color; }" +    ``` + +To watch a file for changes, and compile it as needed, use the `-w` flag: + +    ```bash +    $ plessc -w input-file output-file +    ``` + +Errors from watch mode are written to standard out. + + +## License + +Copyright (c) 2010 Leaf Corcoran, <http://leafo.net/lessphp> + +Permission is hereby granted, free of charge, to any person obtaining +a copy of this software and associated documentation files (the +"Software"), to deal in the Software without restriction, including +without limitation the rights to use, copy, modify, merge, publish, +distribute, sublicense, and/or sell copies of the Software, and to +permit persons to whom the Software is furnished to do so, subject to +the following conditions: + +The above copyright notice and this permission notice shall be +included in all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, +EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF +MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND +NONINFRINGEMENT.
