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

  - popt is fully reentrant;

  - popt can parse arbitrary argv[] style arrays while getopt(3) makes this
    quite difficult;

  - popt allows users to alias command line arguments;

  - popt provides convience functions for parsing strings into argv[] style
    arrays.")
