The pilot-QOF source includes the popt command line option parsing library. While it is similir to getopt(3), it contains a number of enhancements, including:
- popt is fully reentrant
- popt can parse arbitrary argv style arrays while getopt(2) makes this quite difficult
- popt allows users to alias command line arguments
- popt provides convience functions for parsing strings into argv style arrays
popt is used by rpm, the Red Hat install program, and many other Red Hat utilities, all of which provide excellent examples of how to use popt. Complete documentation on popt 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 (availble from Addison Wesley in May, 1998).
