Milestone:  To Be Determined           |   Component:  program_options

---------------------------------------+------------------------------------
 I have a minor feature request and that is that when I write out a program
 option that has an argument it comes out, for example, like this:

 {{{
   -m [ --log-file ] arg (=<none>)         set log file.
 }}}

 But that 'arg' does not look nice to me; I would rather that it read:

 {{{
   -m [ --log-file ] <filename> (=<none>)         set log file.
 }}}

 And I would like to be able to set that somehow in the po::value setup. I
 also checked to see if you could do this already and it seems as though
 you cannot in the boost::program_options source code itself starting on
 line 67 of value_semantic.cpp there is the following lines:

 {{{#!cpp
 BOOST_PROGRAM_OPTIONS_DECL std::string arg("arg");

 std::string
 untyped_value::name() const
 {
     return arg;
 }
 }}}

 So since 'arg' seems to be set in stone I do not think that it is possible
 to do this yet. I would really like to know if you think this is a good
 idea or not. Thanks.
