Summary

0005197: Ability to define --foo= options in Arg

Description

Hello,

It seems that the standard way to define and use command line options is the following:
- one-char options which take an argument are used with the form
  -f myarg
- long options which take an argument are used with the form
  --foo=myarg

But the Arg module doesn't allow to define the second form. It allows only
  --foo myarg

Would it be possible to allow the specification of such options ? Maybe by adding constructors to the Arg.spec type ?

Notes
(0005906) doligez (manager) 2011-05-17 17:04	I don't understand the need to annoy your users by forcing them to type = instead of the large easy-to-find space bar... The best way to implement this without polluting arg.mli too much is probably to add an optional argument to parse and parse_argv to tell them to accept = as a separator between flag and argument.
