-This is the popt 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(2) 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
-
-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).
-
-Comments on popt should be addressed to ewt@redhat.com.
