[Boost-users] [program options] Using similar option strings

   I recent attempted the equivalent of allowing the follwoing two options:
--help
--help-command [arg]
--help-component [arg]

   When I ran the program with --help, I got an error that it was 
ambiguous.  I didn't realize it, but program options allows the user to 
not specify the full string with "--".  This then makes all the options 
above match --help.

   How can I get this type of functionality without getting runtime 
errors about ambiguity?
   If I were to reduce it to just --help and --help-command, it may be 
possible to just do --help with an optional argument, but I don't know 
how to do that.  Currently, I'd like to avoid a shared namespace for 
commands and components.
