Creates a new option context.
The parameter_string can serve multiple purposes. It can be used
to add descriptions for "rest" arguments, which are not parsed by
the GOptionContext, typically something like "FILES" or
"FILE1 FILE2...". If you are using G_OPTION_REMAINING for
collecting "rest" arguments, GLib handles this automatically by
using the arg_description of the corresponding GOptionEntry in
the usage summary.
Another usage is to give a short summary of the program
functionality, like " - frob the strings", which will be displayed
in the same line as the usage. For a longer description of the
program functionality that should be displayed as a paragraph
below the usage line, use g_option_context_set_summary().
Note that the parameter_string is translated using the
function set with g_option_context_set_translate_func(), so
it should normally be passed untranslated.
