popt

This is the popt(3) 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(3) 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

Complete documentation on popt(3) is available in popt.pdf (included in this tarball), which is excerpted with permission from the book "Linux Application Development" by Michael K. Johnson and Erik Troan (available from Addison Wesley in May, 1998).
