Comment (by lukasz.dobrogowski@â¦):
I'm also voting for this. It would largely help with migration from
existing commandline parsing systems in projects to boost::program_options
with as little changes to syntax and usability as possible.
Example from Wesnoth:
fragment of --help before PO:
--preprocess, -p <file/folder> <target directory> (short description)
fragment of --help after using PO:
-p [ --preprocess ] arg (long description, arg has to be explained in it
and it isn't immediately visible that the option takes two tokens)
It's probably most useful for multitoken commands with custom validators,
where it would really help usability to be able to explain needed
arguments with string such as "<myarg1> <myarg2>"...
