Selecting a command within a group hierarchy.
Cmdlang supports grouping subcommands into a nested tree, whereas stdlib.arg works at the level of a command leaves. This module is used to navigate the command tree to select the one based on the prefix of the command line.
For example, given the following command invocation:
./my_command group1 subcommand --flag valuethis module will select from the command tree the subcommand named subcommand from the group group1. It will also return the index at which the parsing should resume, in this case 3 (the index of --flag in Sys.argv).
