/**
* Generates IBM-formatted CL command help documentation.
* This class requires that valid XML and XSL processors (e.g. Xerces and Xalan) be in the CLASSPATH.
*
* CommandHelpRetriever can be run as a command line program, as follows:
*
* java com.ibm.as400.util.CommandHelpRetriever -library <library> -command <command> [ -system <systemName> -userid <userid> -password <password> -showChoicePgmValues -output <outputDirectory> -debug ]
*
* Options:
*
*
*
* -help
* - Displays the help text.
* The -help option may be abbreviated to -h or -?.
*
*
* Parameters:
*
*
*
* -library IBM i library.- Specifies the IBM i library.
* This parameter may be abbreviated
-l or -lib.
*
*
* -command IBM i command.- Specifies the IBM i command.
* This parameter may be abbreviated
-c or -cmd.
*
*
* -system IBM i system name- Specifies the IBM i system. If an IBM i system name is not provided, a signon dialog will be displayed.
* This optional parameter may be abbreviated
-s or -sys.
*
*
* -userid IBM i userID.- Specifies the IBM i userId. If an IBM i userID is not provided, a signon dialog will be displayed.
* This optional parameter may be abbreviated
-u or -uid.
*
*
* -password IBM i password.- Specifies the IBM i password. If an IBM i password is not provided, a signon dialog will be displayed.
* This optional parameter may be abbreviated
-p or -pwd.
*
*
* -showChoicePgmValues [true | false] - Specifies whether or not parameter choices returned from choice programs are shown in the Choices cells of the parameter summary table.
* The default is false.
* This optional parameter may be abbreviated
-scpv.
*
*
* -output output location.
* - Specifies the output location for the generated help. The default is the current directory. The output
* cannot be a file when the command (-c) parameter contains a wildcard (*).
* This optional parameter may be abbreviated
-o.
*
*
* -debug [true | false]
* - Specifies whether to output the source command help and xml files to the output location specified by the -output parameter. The default is false.
* This optional parameter may be abbreviated
-d.
