popt 1.18 Command line option parsing library
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 convenience functions for parsing strings into argv style arrays.
