This is the popt(3) command line option parsing library. While it is similiar 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 convience functions for parsing strings into argv[] style arrays Complete documentation on popt(3) is available in popt.ps (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). Comments on popt should be addressed to popt-devel@rpm5.org.
