+save_ico( $destination );
+````
+
+It takes a source file named `example.gif` and produce an output ICO file named `example.ico`. `example.ico` will contain a single image that is the same size as the source image.
+
+The ICO file format is capable of holding multiple images, each of a different size. The PHP ICO library opens up this feature of the ICO format as shown in the following example:
+
+```php
+require( dirname( __FILE__ ) . '/class-php-ico.php' );
+
+$source = dirname( __FILE__ ) . '/example.gif';
+$destination = dirname( __FILE__ ) . '/example.ico';
+
+$ico_lib = new PHP_ICO( $source, array( array( 32, 32 ), array( 64, 64 ) ) );
+$ico_lib->save_ico( $destination );
+```
+
+As with the previous example, this example produces `example.ico` from the `example.gif` source file. In this example, sizes were passed to the constructor that result in the `example.ico` file containing two images: one that is 32x32 and one that is 64x64. Since the same source image is used for each of the contained images, each contained image is simply the source image scaled to the new dimensions.
+
+Using different source images for the different sizes contained inside an ICO file can create much better results. For instance, you can use a high-quality image for higher-resolution images and use smaller images that are tailored for their specific dimensions for the smaller sizes. The following example shows how the PHP ICO library can be used to create such ICO files:
+
+```php
+require( dirname( __FILE__ ) . '/class-php-ico.php' );
+
+$destination = dirname( __FILE__ ) . '/example.ico';
+
+$ico_lib = new PHP_ICO();
+
+$ico_lib->add_image( dirname( __FILE__ ) . '/example-small.gif', array( array( 16, 16 ), array( 24, 24 ), array( 32, 32 ) ) );
+$ico_lib->add_image( dirname( __FILE__ ) . '/example-medium.gif', array( array( 48, 48 ), array( 96, 96 ) ) );
+$ico_lib->add_image( dirname( __FILE__ ) . '/example-large.gif', array( array( 128, 128 ) ) );
+
+$ico_lib->save_ico( $destination );
+```
+
+This example creates a single ICO file named `example.ico` just as the previous examples. The difference is that this example used multiple source images to generate the final ICO images. The final ICO image contains a total of six images: 16x16, 24x24, and 32x32 images from `example-small.gif`; 48x48 and 96x96 images from `example-medium.gif`; and a 128x128 image from `example-large.gif`.
+
+By using this feature of supplying multiple source images with specific sizes for each, you can generate ICO files that have very high-quality images at each supplied resolution.
+
+Since the PHP ICO library was created to generate favicon files, the following example shows how to generate a favicon ICO file with all the needed dimensions from a single source image:
+
+```php
+require( dirname( __FILE__ ) . '/class-php-ico.php' );
+
+$source = dirname( __FILE__ ) . '/example.gif';
+$destination = dirname( __FILE__ ) . '/example.ico';
+
+$sizes = array(
+ array( 16, 16 ),
+ array( 24, 24 ),
+ array( 32, 32 ),
+ array( 48, 48 ),
+);
+
+$ico_lib = new PHP_ICO( $source, $sizes );
+$ico_lib->save_ico( $destination );
+```
+
+I've found that the 16x16, 24x24, 32x32, and 48x48 image sizes cover all the sizes that browsers and Windows will try to use a favicon image for. The different sizes come from using the favicon for various browser icons, bookmarks, and various other places.
+
+Thanks
+------
+
+I'd like to thank [iThemes](http://ithemes.com) for making this project possible. This code was originally developed to add easy-to-use favicon support to the [Builder theme](http://ithemes.com/purchase/builder-theme/). I asked [Cory](http://corymiller.tv/), owner of iThemes and my boss, if I could share the final code. He gave me the green light. Win for everyone. :)
+
+Thanks iThemes. Thanks Cory.

+
+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) 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
+this service 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 make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. 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.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+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
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the 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 a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+
+ Copyright (C)
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License along
+ with this program; if not, write to the Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ , 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+# How to contribute
+
+
+## Issues
+
+When [filing bugs](https://github.com/matthiasmullie/minify/issues/new),
+try to be as thorough as possible:
+* What version did you use?
+* What did you try to do? ***Please post the relevant parts of your code.***
+* What went wrong? ***Please include error messages, if any.***
+* What was the expected result?
+
+
+## Pull requests
+
+Bug fixes and general improvements to the existing codebase are always welcome.
+New features are also welcome, but will be judged on an individual basis. If
+you'd rather not risk wasting your time implementing a new feature only to see
+it turned down, please start the discussion by
+[opening an issue](https://github.com/matthiasmullie/minify/issues/new).
+
+Don't forget to add your changes to the [changelog](CHANGELOG.md).
+
+
+### Testing
+
+Please include tests for every change or addition to the code.
+To run the complete test suite:
+
+```sh
+vendor/bin/phpunit
+```
+
+When submitting a new pull request, please make sure that that the test suite
+passes (Travis CI will run it & report back on your pull request.)
+
+To run the tests on Windows, run `tests/convert_symlinks_to_windows_style.sh`
+from the command line in order to convert Linux-style test symlinks to
+Windows-style.
+
+
+### Coding standards
+
+All code must follow [PSR-2](http://www.php-fig.org/psr/psr-2/). Just make sure
+to run php-cs-fixer before submitting the code, it'll take care of the
+formatting for you:
+
+```sh
+vendor/bin/php-cs-fixer fix src
+vendor/bin/php-cs-fixer fix tests
+```
+
+Document the code thoroughly!
+
+
+## License
+
+Note that minify is MIT-licensed, which basically allows anyone to do
+anything they like with it, without restriction.

+# Revision History
+
+## 8.0
+
+### 8.0.0 (2016-06-30)
+
+* Store source CSS line numbers in tokens and parsing exceptions.
+* *No deprecations*
+
+#### Backwards-incompatible changes
+
+* Unrecoverable parser errors throw an exception of type `Sabberworm\CSS\Parsing\SourceException` instead of `\Exception`.
+
+### 8.1.0 (2016-07-19)
+
+* Comments are no longer silently ignored but stored with the object with which they appear (no render support, though). Thanks to @FMCorz.
+* The IE hacks using `\0` and `\9` can now be parsed (and rendered) in lenient mode. Thanks (again) to @FMCorz.
+* Media queries with or without spaces before the query are parsed. Still no *real* parsing support, though. Sorry…
+* PHPUnit is now listed as a dev-dependency in composer.json.
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+### 8.2.0 (2018-07-13)
+
+* Support parsing `calc()`, thanks to @raxbg.
+* Support parsing grid-lines, again thanks to @raxbg.
+* Support parsing legacy IE filters (`progid:`) in lenient mode, thanks to @FMCorz
+* Performance improvements parsing large files, again thanks to @FMCorz
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+### 8.3.0 (2019-02-22)
+
+* Refactor parsing logic to mostly reside in the class files whose data structure is to be parsed (this should eventually allow us to unit-test specific parts of the parsing logic individually).
+* Fix error in parsing `calc` expessions when the first operand is a negative number, thanks to @raxbg.
+* Support parsing CSS4 colors in hex notation with alpha values, thanks to @raxbg.
+* Swallow more errors in lenient mode, thanks to @raxbg.
+* Allow specifying arbitrary strings to output before and after declaration blocks, thanks to @westonruter.
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 7.0
+
+### 7.0.0 (2015-08-24)
+
+* Compatibility with PHP 7. Well timed, eh?
+* *No deprecations*
+
+#### Backwards-incompatible changes
+
+* The `Sabberworm\CSS\Value\String` class has been renamed to `Sabberworm\CSS\Value\CSSString`.
+
+### 7.0.1 (2015-12-25)
+
+* No more suppressed `E_NOTICE`
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+### 7.0.2 (2016-02-11)
+
+* 150 time performance boost thanks to @[ossinkine](https://github.com/ossinkine)
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+### 7.0.3 (2016-04-27)
+
+* Fixed parsing empty CSS when multibyte is off
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 6.0
+
+### 6.0.0 (2014-07-03)
+
+* Format output using Sabberworm\CSS\OutputFormat
+* *No backwards-incompatible changes*
+
+#### Deprecations
+
+* The parse() method replaces __toString with an optional argument (instance of the OutputFormat class)
+
+### 6.0.1 (2015-08-24)
+
+* Remove some declarations in interfaces incompatible with PHP 5.3 (< 5.3.9)
+* *No deprecations*
+
+## 5.0
+
+### 5.0.0 (2013-03-20)
+
+* Correctly parse all known CSS 3 units (including Hz and kHz).
+* Output RGB colors in short (#aaa or #ababab) notation
+* Be case-insensitive when parsing identifiers.
+* *No deprecations*
+
+#### Backwards-incompatible changes
+

+* *No backwards-incompatible changes*
+* *No deprecations*
+
+### 5.0.5 (2013-04-17)

+* Support removing a selector from a declaration block using `$oBlock->removeSelector($mSelector)`
+* Introduce a specialized exception (Sabberworm\CSS\Parsing\OuputException) for exceptions during output rendering
+
+* *No deprecations*
+
+#### Backwards-incompatible changes
+
+* Outputting a declaration block that has no selectors throws an OuputException instead of outputting an invalid ` {…}` into the CSS document.
+
+## 4.0
+
+### 4.0.0 (2013-03-19)
+
+* Support for more @-rules

+* `Sabberworm\CSS\CSSList\MediaQuery` renamed to `Sabberworm\CSS\RuleSet\CSSList\AtRuleBlockList` with differing semantics and API (which also works for other block-list-based @-rules like `@supports`).
+
+## 3.0
+
+### 3.0.0 (2013-03-06)
+
+* Support for lenient parsing (on by default)
+* *No deprecations*
+
+#### Backwards-incompatible changes
+
+* All properties (like whether or not to use `mb_`-functions, which default charset to use and – new – whether or not to be forgiving when parsing) are now encapsulated in an instance of `Sabberworm\CSS\Settings` which can be passed as the second argument to `Sabberworm\CSS\Parser->__construct()`.
+* Specifying a charset as the second argument to `Sabberworm\CSS\Parser->__construct()` is no longer supported. Use `Sabberworm\CSS\Settings::create()->withDefaultCharset('some-charset')` instead.
+* Setting `Sabberworm\CSS\Parser->bUseMbFunctions` has no effect. Use `Sabberworm\CSS\Settings::create()->withMultibyteSupport(true/false)` instead.
+* `Sabberworm\CSS\Parser->parse()` may throw a `Sabberworm\CSS\Parsing\UnexpectedTokenException` when in strict parsing mode.
+
+## 2.0
+
+### 2.0.0 (2013-01-29)
+
+* Allow multiple rules of the same type per rule set
+
+#### Backwards-incompatible changes
+
+* `Sabberworm\CSS\RuleSet->getRules()` returns an index-based array instead of an associative array. Use `Sabberworm\CSS\RuleSet->getRulesAssoc()` (which eliminates duplicate rules and lets the later rule of the same name win).
+* `Sabberworm\CSS\RuleSet->removeRule()` works as it did before except when passed an instance of `Sabberworm\CSS\Rule\Rule`, in which case it would only remove the exact rule given instead of all the rules of the same type. To get the old behaviour, use `Sabberworm\CSS\RuleSet->removeRule($oRule->getRule()`;
+
+## 1.0
+
+Initial release of a stable public API.
+
+## 0.9
+
+Last version not to use PSR-0 project organization semantics.

+PHP CSS Parser
+--------------
+
+[](https://travis-ci.org/sabberworm/PHP-CSS-Parser) [](http://hhvm.h4cc.de/package/sabberworm/php-css-parser)
+
+A Parser for CSS Files written in PHP. Allows extraction of CSS files into a data structure, manipulation of said structure and output as (optimized) CSS.
+
+## Usage
+
+### Installation using composer
+
+Add php-css-parser to your composer.json
+
+```json
+{
+ "require": {
+ "sabberworm/php-css-parser": "*"
+ }
+}
+```
+
+### Extraction
+
+To use the CSS Parser, create a new instance. The constructor takes the following form:
+
+```php
+new Sabberworm\CSS\Parser($sText);
+```
+
+To read a file, for example, you’d do the following:
+
+```php
+$oCssParser = new Sabberworm\CSS\Parser(file_get_contents('somefile.css'));
+$oCssDocument = $oCssParser->parse();
+```
+
+The resulting CSS document structure can be manipulated prior to being output.
+
+### Options
+
+#### Charset
+
+The charset option is used only if no @charset declaration is found in the CSS file. UTF-8 is the default, so you won’t have to create a settings object at all if you don’t intend to change that.
+
+```php
+$oSettings = Sabberworm\CSS\Settings::create()->withDefaultCharset('windows-1252');
+new Sabberworm\CSS\Parser($sText, $oSettings);
+```
+
+#### Strict parsing
+
+To have the parser choke on invalid rules, supply a thusly configured Sabberworm\CSS\Settings object:
+
+```php
+$oCssParser = new Sabberworm\CSS\Parser(file_get_contents('somefile.css'), Sabberworm\CSS\Settings::create()->beStrict());
+```
+
+#### Disable multibyte functions
+
+To achieve faster parsing, you can choose to have PHP-CSS-Parser use regular string functions instead of `mb_*` functions. This should work fine in most cases, even for UTF-8 files, as all the multibyte characters are in string literals. Still it’s not recommended to use this with input you have no control over as it’s not thoroughly covered by test cases.
+
+```php
+$oSettings = Sabberworm\CSS\Settings::create()->withMultibyteSupport(false);
+new Sabberworm\CSS\Parser($sText, $oSettings);
+```
+
+### Manipulation
+
+The resulting data structure consists mainly of five basic types: `CSSList`, `RuleSet`, `Rule`, `Selector` and `Value`. There are two additional types used: `Import` and `Charset` which you won’t use often.
+
+#### CSSList
+
+`CSSList` represents a generic CSS container, most likely containing declaration blocks (rule sets with a selector) but it may also contain at-rules, charset declarations, etc. `CSSList` has the following concrete subtypes:
+
+* `Document` – representing the root of a CSS file.
+* `MediaQuery` – represents a subsection of a CSSList that only applies to a output device matching the contained media query.
+
+To access the items stored in a `CSSList` – like the document you got back when calling `$oCssParser->parse()` –, use `getContents()`, then iterate over that collection and use instanceof to check whether you’re dealing with another `CSSList`, a `RuleSet`, a `Import` or a `Charset`.
+
+To append a new item (selector, media query, etc.) to an existing `CSSList`, construct it using the constructor for this class and use the `append($oItem)` method.
+
+#### RuleSet
+
+`RuleSet` is a container for individual rules. The most common form of a rule set is one constrained by a selector. The following concrete subtypes exist:
+
+* `AtRuleSet` – for generic at-rules which do not match the ones specifically mentioned like @import, @charset or @media. A common example for this is @font-face.
+* `DeclarationBlock` – a RuleSet constrained by a `Selector`; contains an array of selector objects (comma-separated in the CSS) as well as the rules to be applied to the matching elements.
+
+Note: A `CSSList` can contain other `CSSList`s (and `Import`s as well as a `Charset`) while a `RuleSet` can only contain `Rule`s.
+
+If you want to manipulate a `RuleSet`, use the methods `addRule(Rule $oRule)`, `getRules()` and `removeRule($mRule)` (which accepts either a Rule instance or a rule name; optionally suffixed by a dash to remove all related rules).
+
+#### Rule
+
+`Rule`s just have a key (the rule) and a value. These values are all instances of a `Value`.
+
+#### Value
+
+`Value` is an abstract class that only defines the `render` method. The concrete subclasses for atomic value types are:
+
+* `Size` – consists of a numeric `size` value and a unit.
+* `Color` – colors can be input in the form #rrggbb, #rgb or schema(val1, val2, …) but are always stored as an array of ('s' => val1, 'c' => val2, 'h' => val3, …) and output in the second form.
+* `CSSString` – this is just a wrapper for quoted strings to distinguish them from keywords; always output with double quotes.
+* `URL` – URLs in CSS; always output in URL("") notation.
+
+There is another abstract subclass of `Value`, `ValueList`. A `ValueList` represents a lists of `Value`s, separated by some separation character (mostly `,`, whitespace, or `/`). There are two types of `ValueList`s:
+
+* `RuleValueList` – The default type, used to represent all multi-valued rules like `font: bold 12px/3 Helvetica, Verdana, sans-serif;` (where the value would be a whitespace-separated list of the primitive value `bold`, a slash-separated list and a comma-separated list).
+* `CSSFunction` – A special kind of value that also contains a function name and where the values are the function’s arguments. Also handles equals-sign-separated argument lists like `filter: alpha(opacity=90);`.
+
+#### Convenience methods
+
+There are a few convenience methods on Document to ease finding, manipulating and deleting rules:
+
+* `getAllDeclarationBlocks()` – does what it says; no matter how deeply nested your selectors are. Aliased as `getAllSelectors()`.
+* `getAllRuleSets()` – does what it says; no matter how deeply nested your rule sets are.
+* `getAllValues()` – finds all `Value` objects inside `Rule`s.
+
+## To-Do
+
+* More convenience methods [like `selectorsWithElement($sId/Class/TagName)`, `attributesOfType($sType)`, `removeAttributesOfType($sType)`]
+* Real multibyte support. Currently only multibyte charsets whose first 255 code points take up only one byte and are identical with ASCII are supported (yes, UTF-8 fits this description).
+* Named color support (using `Color` instead of an anonymous string literal)
+
+## Use cases
+
+### Use `Parser` to prepend an id to all selectors
+
+```php
+$sMyId = "#my_id";
+$oParser = new Sabberworm\CSS\Parser($sText);
+$oCss = $oParser->parse();
+foreach($oCss->getAllDeclarationBlocks() as $oBlock) {
+ foreach($oBlock->getSelectors() as $oSelector) {
+ //Loop over all selector parts (the comma-separated strings in a selector) and prepend the id
+ $oSelector->setSelector($sMyId.' '.$oSelector->getSelector());
+ }
+}
+```
+
+### Shrink all absolute sizes to half
+
+```php
+$oParser = new Sabberworm\CSS\Parser($sText);
+$oCss = $oParser->parse();
+foreach($oCss->getAllValues() as $mValue) {
+ if($mValue instanceof CSSSize && !$mValue->isRelative()) {
+ $mValue->setSize($mValue->getSize()/2);
+ }
+}
+```
+
+### Remove unwanted rules
+
+```php
+$oParser = new Sabberworm\CSS\Parser($sText);
+$oCss = $oParser->parse();
+foreach($oCss->getAllRuleSets() as $oRuleSet) {
+ $oRuleSet->removeRule('font-'); //Note that the added dash will make this remove all rules starting with font- (like font-size, font-weight, etc.) as well as a potential font-rule
+ $oRuleSet->removeRule('cursor');
+}
+```
+
+### Output
+
+To output the entire CSS document into a variable, just use `->render()`:
+
+```php
+$oCssParser = new Sabberworm\CSS\Parser(file_get_contents('somefile.css'));
+$oCssDocument = $oCssParser->parse();
+print $oCssDocument->render();
+```
+
+If you want to format the output, pass an instance of type `Sabberworm\CSS\OutputFormat`:
+
+```php
+$oFormat = Sabberworm\CSS\OutputFormat::create()->indentWithSpaces(4)->setSpaceBetweenRules("\n");
+print $oCssDocument->render($oFormat);
+```
+
+Or use one of the predefined formats:
+
+```php
+print $oCssDocument->render(Sabberworm\CSS\OutputFormat::createPretty());
+print $oCssDocument->render(Sabberworm\CSS\OutputFormat::createCompact());
+```
+
+To see what you can do with output formatting, look at the tests in `tests/Sabberworm/CSS/OutputFormatTest.php`.

+# scssphp
+###
+
+[](http://travis-ci.org/scssphp/scssphp)
+[](https://packagist.org/packages/scssphp/scssphp)
+
+`scssphp` is a compiler for SCSS written in PHP.
+
+Checkout the homepage, , for directions on how to use.
+
+## Running Tests
+
+`scssphp` uses [PHPUnit](https://github.com/sebastianbergmann/phpunit) for testing.
+
+Run the following command from the root directory to run every test:
+
+ vendor/bin/phpunit tests
+
+There are several tests in the `tests/` directory:
+
+* `ApiTest.php` contains various unit tests that test the PHP interface.
+* `ExceptionTest.php` contains unit tests that test for exceptions thrown by the parser and compiler.
+* `FailingTest.php` contains tests reported in Github issues that demonstrate compatibility bugs.
+* `InputTest.php` compiles every `.scss` file in the `tests/inputs` directory
+ then compares to the respective `.css` file in the `tests/outputs` directory.
+* `ScssTest.php` extracts (ruby) `scss` tests from the `tests/scss_test.rb` file.
+* `ServerTest.php` contains functional tests for the `Server` class.
+
+When changing any of the tests in `tests/inputs`, the tests will most likely
+fail because the output has changed. Once you verify that the output is correct
+you can run the following command to rebuild all the tests:
+
+ BUILD=1 vendor/bin/phpunit tests
+
+This will compile all the tests, and save results into `tests/outputs`.
+
+To enable the `scss` compatibility tests:
+
+ TEST_SCSS_COMPAT=1 vendor/bin/phpunit tests
+
+## Coding Standard
+
+`scssphp` source conforms to [PSR2](http://www.php-fig.org/psr/psr-2/).
+
+Run the following command from the root directory to check the code for "sniffs".
+
+ vendor/bin/phpcs --standard=PSR2 bin src tests

+ *
+ * This parser is most similar to a recursive descent parser. Single
+ * functions represent discrete grammatical rules for the language, and
+ * they are able to capture the text that represents those rules.
+ *
+ * Consider the function Compiler::keyword(). (All parse functions are
+ * structured the same.)
+ *
+ * The function takes a single reference argument. When calling the
+ * function it will attempt to match a keyword on the head of the buffer.
+ * If it is successful, it will place the keyword in the referenced
+ * argument, advance the position in the buffer, and return true. If it
+ * fails then it won't advance the buffer and it will return false.
+ *
+ * All of these parse functions are powered by Compiler::match(), which behaves
+ * the same way, but takes a literal regular expression. Sometimes it is
+ * more convenient to use match instead of creating a new function.
+ *
+ * Because of the format of the functions, to parse an entire string of
+ * grammatical rules, you can chain them together using &&.
+ *
+ * But, if some of the rules in the chain succeed before one fails, then
+ * the buffer position will be left at an invalid state. In order to
+ * avoid this, Compiler::seek() is used to remember and set buffer positions.
+ *
+ * Before parsing a chain, use $s = $this->count to remember the current
+ * position into $s. Then if a chain fails, use $this->seek($s) to
+ * go back where we started.
