Subject: [Boost-users] feature request: program_options: generate OS dependent options

Following the discussion in
http://lists.boost.org/boost-users/2009/12/54327.php, let me then request
that the feature be implemented in program_options.
The 2 systems that I know a little about are POSIX(thanks Ovanes) and
.POSIX: Typically, the command line would options with the '-' being the
delimiter, like for the 'ls' program on a linux system:
-a, --all do not ignore entries starting with .
-A, --almost-all do not list implied . and ..
--author with -l, print the author of each file
-b, --escape print octal escapes for nongraphic characters
--block-size=SIZE use SIZE-byte blocks
--help print this
dir /?: Typically, the '/' is the delimiter.
/B Uses bare format (no heading information or summary).
So in fact, I have 2 feature requests :-) :
1. Detect automatically the OS platform and the appropriate delimiter ( / or
- or -- ) for win or POSIX
2. Detect the special option (help) that dislays the usage, which is /? on
windows and --help on POSIX, and treat it symbolically in the user code
calling program_options, ie not having to test for the "help" string as
shown in the tutorial.
I can create the trac tickets if preferred,
