Example usage of gab-cmdline

Example 1

ant [options] [target [target2 [target3] ...]]
  Options: 
  -help                  print this message
  -projecthelp           print project help information
  -version               print the version information and exit
  -quiet                 be extra quiet
  -verbose               be extra verbose
  -debug                 print debugging information
  -emacs                 produce logging information without adornments
  -logfile <file>        use given file for log
  -logger <classname>    the class which is to perform logging
  -listener <classname>  add an instance of class as a project listener
  -buildfile <file>      use given buildfile
  -D<property>=<value>   use value for given property
  -find <file>           search for buildfile towards the root of the
                         filesystem and use it

CmdLine.defineCommand("-help, #print this message")
       .defineCommand("-projectHelp, #print project help information")
       .defineCommand("-version, #print the version information and exit")
       .defineCommand("-quiet, #be extra quiet")
       .defineCommand("-verbose, #be extra verbose")
       .defineCommand("-debug, #print debugging information")
       .defineCommand("-emacs, #produce logging information without adornments")
       .defineCommand("-logfile, !logFile, #use given file for log")
       .defineCommand("-logger, !logClass, #the class which is to perform logging")
       .defineCommand("-listener, !listenerClass, #add an instance of class as a project listener")
       .defineCommand("-buildfile, !buildFile, #use given buildfile")
       .defineCommand("-find, !buildFile, #search for buildfile towards the root of the filesystem and use it");

Note:  The format of "-D<property>=<value>" is automatically supported and doesnt need to be defined.  
If a -D<property>=<value> is seen on the command line, it is parsed and set 
in the System properties.  In addition, a command is created and sent to the listener.

CmdLine.parse( args, listener );

Example 2

c:\> myapp --install file0.txt

CmdLine.setCommandListener(listener);

CmdLine.defineCommand("-i, --install, !installFileName, :file[0-9].txt, #install something");

CmdLine.parse( args );

Example 3

c:\> myapp -install=file1.txt

CmdLine.defineCommand("-install, !installFileName, :file[0-9].txt, #install something")
       .setCommandListener(listener)
       .parse( args );

Example 4

myapp -classpath=c:/myapps

CmdLine.defineCommand("-classpath, !classpath, :c:/\\w+, #define the class path")
       .parse( args, listener );

Example 5

c:\> myapp implicit=class

CmdLine.defineCommand("implicit, !implicit, :class|interface|none, #imark a class, interface or none as implicit.")
       .parse( args, listener );

Example 6

c:\> myapp --file=myfilename.txt

CmdLine.defineCommand("--file, !fileName, :\\w+.txt, #the file name to load.")
       .parse( args, listener );

Example 7

c:\> myapp f myfilename.txt
c:\> myapp file myfilename.txt
c:\> myapp filename myfilename.txt

CmdLine.defineCommand("f, file, filename, !fileName, :\\w+.txt, #the file name to load.")
       .parse( args, listener );
