OptionParser
Introduction
OptionParser is a class for command-line option analysis. It is much more advanced, yet also easier to use, than GetoptLong, and is a more Ruby-oriented solution.
Features
-
The argument specification and the code to handle it are written in the same place.
-
It can output an option summary; you don't need to maintain this string separately.
-
Optional and mandatory arguments are specified very gracefully.
