Generates code that parses command line options
Opag (Option Parser Generator) generates C or C++ code that parses command line options. Input is a description of the command line options you want your program to support. Output is a C or C++ function which finds these options in an array of strings (typically "argv", the second parameter of the "main" function) and sets variables accordingly. The package supports both short (single character) and long (GNU style) options. Users can also associate a help string with each option. Opag uses these to create a macro which expands to a string containing a nicely formatted description of the options.
