Definition of the command line interface

This module uses M_CLI2 to define the command line interface. To define a command line interface create a new command settings type from the fpm_cmd_settings base class or the respective parent command settings.

The subcommand is selected by the first non-option argument in the command line. In the subcase block the actual command line is defined and transferred to an instance of the fpm_cmd_settings, the actual type is used by the fpm main program to determine which command entry point is chosen.

To add a new subcommand add a new case to select construct and specify the wanted command line and the expected default values. Some of the following points also apply if you add a new option or argument to an existing fpm subcommand. At this point you should create a help page for the new command in a simple catman-like format as well in the set_help procedure. Make sure to register new subcommands in the fpm-manual command by adding them to the manual character array and in the help/manual case as well. You should add the new command to the synopsis section of the fpm-list, fpm-help and fpm --list help pages below to make sure the help output is complete and consistent as well.
