 * The model for all the configuration options supported by the compiler. Each option is stored in a private field. It
 * usually has a getter method, a setter method and a configuration method (started with "cfg"). The configuration
 * methods are used by the configurators to set the values of a given option name.
 * <p>
 * This class is currently being reviewed and refactored. See CMP-471 as the master bug for the tasks.
 * <p>
 * Steps to refactor:
 * <ol>
 * <li>Check "mxmlc" manual (http://adobe.ly/bffN8A) and copy documents to Javadoc on setters of options.</li>
 * <li>Check "configuration support" WIKI (http://bit.ly/oAI8gj) to see if an option should be deprecated.</li>
 * <li>Merge {@code cfgXXX} to {@code setXXX}, and annotate the setter.</li>
 * <li>Remove {@code getXXXInfo()} static method.</li>

     * when compiling against an RSL using the runtime-shared-libraries option.

     * verify the existence of the SWF file at this location at compile time. It does store this string in the
     * application, however, and uses it at run time. As a result, the SWF file must be available at run time but
     * necessarily not at compile time.
     * <p>
     * The policy-file-url is the location of the crossdomain.xml file that gives permission to read the RSL from the

     * http://www.mydomain.com/rsls/crossdomain.xml.

     * The failover-url and second policy-file-url arguments specify the location of the secondary RSL and
     * crossdomain.xml file if the first RSL cannot be loaded. This most commonly happens when the client Player version
     * does not support cross-domain RSLs. You can add any number of failover RSLs, but must include a policy file URL
     * for each one.
     * <p>
     * Do not include spaces between the comma-separated values. The following example shows how to use this option:
     * 
     * <pre>
     * mxmlc -o=../lib/app.swf -runtime-shared-library-path=../lib/mylib.swc,../bin/myrsl.swf Main.mxml
     * </pre>
     * 
     * You can specify more than one library file to be used as an RSL. You do this by adding additional
     * runtime-shared-library-path options.
     * <p>
     * You can also use the runtime-shared-libraries command to use RSLs with your applications. However, the
     * runtime-shared-library-path option lets you also specify the location of the policy file and failover RSL.

     * evaluated, at compile-time, to <code>false</code>.
     *
     * It is good practice to wrap values with double-quotes, so that MXMLC correctly parses them as a single argument:
     * <br/>
     * <code>-define=TEST::oneShiftRightTwo,"1 >> 2"</code>

     *
     * String values on the command-line <i>must</i> be surrounded by double-quotes, and either escape-quoted (
     * <code>"\"foo\""</code> or <code>"\'foo\'"</code>) or single-quoted (<code>"'foo'"</code>).
     *
     * String values in configuration files need only be single- or double- quoted:<br/>

     * <code>""</code> in configuration files.
     * 
     * Finally, if you have existing definitions in a configuration file, and you would like to add to them with the
     * command-line (let's say most of your build setCompilertings are in the configuration, and that you are adding one
     * temporarily using the command-line), you use the following syntax: <code>-define+=TEST::temporary,false</code>
     * (noting the plus sign)
     * 
     * Note that definitions can be overridden/redefined if you use the append ("+=") syntax (on the commandline or in a
     * user config file, for instance) with the same namespace and name, and a new value.
     * 
     * Definitions cannot be removed/undefined. You can undefine ALL existing definitions from (e.g. from
     * flex-config.xml) if you do not use append syntax ("=" or append="false").
     * 
     * IMPORTANT FOR FLEXBUILDER If you are using "Additional commandline arguments" to "-define", don't use the
     * following syntax though I suggest it above: -define+=CONFIG::foo,"'value'" The trouble is that FB parses the
     * double quotes incorrectly as <"'value'> -- the trailing double-quote is dropped. The solution is to avoid inner
     * double-quotes and put them around the whole expression: -define+="CONFIG::foo,'value'"
