Hi all, I was trying to figure out if there is a way to make the short options use more than one letter to create an abbrieviation. For example: desc.add_options() ("resolution","re","Choose resolution") ("raster-level,"rl","Chhose raster mode") .... I know that by convention and definition, short options are just -(letter), so that when you ask to print help, you get something like: -r [--resolution] arg -r [--raster-level] arg but I would like to find a way to have -re [--resolution] arg -rl [--raster-level] arg Point is, I have some options that start with the same letter, so being able to make short abbreivations or acronyms for them would be helpful. If this is possible, it isn't real clear to me how, and I haven't turned up much in google. Any suggestions? Thanks!
