getopt(3)-like library with a number of enhancements
This is the popt command line option parsing library. While it is similar
to getopt(3), it contains a number of enhancements, including:

        1) popt is fully reentrant
        2) popt can parse arbitrary argv[] style arrays while
           getopt(2) makes this quite difficult
        3) popt allows users to alias command line arguments
        4) popt provides convenience functions for parsing strings
           into argv[] style arrays
