 POSIX systems usually use - or -- as a "delimiter" when reading options
 from command lines. For e.g. the 'ls' program on a linux system:

 {{{
   ls --help
   ....
   -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
   ....
 }}}


 Windows usually uses the / character instead, for e.g. for dir:
 dir /?: Typically, the '/' is the delimiter.
 {{{
   ...
   /B          Uses bare format (no heading information or summary).
   ...
 }}}

 It would be useful to have the library recognize the platform on which it
 is begin compiled (or even better, the platform being targeted) and use
 the default for that platform for reading options from the command line.
