For information about the command-line debugger, see Using the Command-Line Debugger (http://livedocs.adobe.com/flex/2/docs/00001540.html#181846).

Determines whether to keep the generated ActionScript class files.

The generated class files include stubs and classes that are generated by the compiler and used to build the SWF file.

The default location of the files is the /generated subdirectory, which is directly below the target MXML file. If the /generated directory does not exist, the compiler creates one.

      add_param(:library_path, :files) do |p|
        p.description =<<EOF
Links SWC files to the resulting application SWF file. The compiler only links in those classes for the SWC file that are required.

The default value of the library-path option includes all SWC files in the libs directory and the current locale. These are required.

To point to individual classes or packages rather than entire SWC files, use the source-path option.

If you set the value of the library-path as an option of the command-line compiler, you must also explicitly add the framework.swc and locale SWC files. Your new entry is not appended to the library-path but replaces it.

You can use the += operator to append the new argument to the list of existing SWC files.

In a configuration file, you can set the append attribute of the library-path tag to true to indicate that the values should be appended to the library path rather than replace it.

This is an advanced option.

      add_param(:load_config, :file) do |p|
        p.description =<<EOF
Specifies the location of the configuration file that defines compiler options.

If you specify a configuration file, you can override individual options by setting them on the command line.

All relative paths in the configuration file are relative to the location of the configuration file itself.

Use the += operator to chain this configuration file to other configuration files.

        p.description =<<EOF
Specifies the location of an XML file that contains <def>, <pre>, and <ext> symbols to omit from linking when compiling a SWF file. The XML file uses the same syntax as the one produced by the link-report option. For more information on the report, see Examining linker dependencies (http://livedocs.adobe.com/flex/2/docs/00001394.html#211202).

This option provides compile-time link checking for external components that are dynamically linked.

Specifies the locale that should be packaged in the SWF file (for example, en_EN). You run the mxmlc compiler multiple times to create SWF files for more than one locale, with only the locale option changing.

You must also include the parent directory of the individual locale directories, plus the token {locale}, in the source-path; for example:

mxmlc -locale en_EN -source-path locale/{locale} -file-specs MainApp.mxml

      add_param(:output, :file) do |p|
        p.description =<<EOF
Specifies the output path and filename for the resulting file. If you omit this option, the compiler saves the SWF file to the directory where the target file is located.

The default SWF filename matches the target filename, but with a SWF file extension.

If you use a relative path to define the filename, it is always relative to the current working directory, not the target MXML application root.

The compiler creates extra directories based on the specified filename if those directories are not present.

Specifies a list of run-time shared libraries (RSLs) to use for this application. RSLs are dynamically-linked at run time.

You specify the location of the SWF file relative to the deployment location of the application. For example, if you store a file named library.swf file in the web_root/libraries directory on the web server, and the application in the web root, you specify libraries/library.swf.

Adds directories or files to the source path. The Flex compiler searches directories in the source path for MXML or AS source files that are used in your Flex applications and includes those that are required at compile time.

You can use wildcards to include all files and subdirectories of a directory.

To link an entire library SWC file and not individual classes or directories, use the library-path option.

The source path is also used as the search path for the component compiler's include-classes and include-resource-bundles options.

You can also use the += operator to append the new argument to the list of existing source path entries.
