[Boost-users] [program_options] option mnemonics

In addition to the ability to define a long and short (one character)
name for an option, is there a way to provide an "in-between" name?
This way an alias, acronym, or mnemonic version could be provided.

For example:

   desc.add_options()
     ( "very-long-option-name,vlon,v", value< string >, "a long option name" )
     ;

and

   cout << desc would print something like:

   -v | -vlon | --very-long-option-name arg   : a long option name

I would also not mind giving up the single-character version in favor
of a mnemonic:

   desc.add_options()
     ( "very-long-option-name,vlon", value< string >, "a long option name" )
     ;

   cout << desc would print:

   -vlon [--very-long-option-name]  arg  : a long option name
