+1.5 -> 1.6
+ - add ability to perform callbacks for every, not just first, match.
+
+1.3 -> 1.5
+ - heavy dose of const's
+ - poptParseArgvString() now NULL terminates the list
+
+1.2.3 -> 1.3
+ - added support for single -
+ - misc bug fixes
+ - portability improvements
+
+1.2.2 -> 1.2.3
+ - fixed memset() in help message generation (Dale Hawkins)
+ - added extern "C" stuff to popt.h for C++ compilers (Dale Hawkins)
+ - const'ified poptParseArgvString (Jeff Garzik)
+
+1.2.1 -> 1.2.2
+ - fixed bug in chaind alias happens which seems to have only
+ affected --triggers in rpm
+ - added POPT_ARG_VAL
+ - popt.3 installed by default
+
+1.2 -> 1.2.1
+ - added POPT_ARG_INTL_DOMAIN (Elliot Lee)
+ - updated Makefile's to be more GNUish (Elliot Lee)
+
+1.1 -> 1.2
+ - added popt.3 man page (Robert Lynch)
+ - don't use mmap anymore (its lack of portability isn't worth the
+ trouble)
+ - added test script
+ - added support for exec
+ - removed support for *_POPT_ALIASES env variable -- it was a bad
+ idea
+ - reorganized into multiple source files
+ - added automatic help generation, POPT_AUTOHELP
+ - added table callbacks
+ - added table inclusion
+ - updated man page for new features
+ - added test scripts
+
+1.0 -> 1.1

+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 (available
+from Addison Wesley in May, 1998).
+
+Comments on popt should be addressed to ewt@redhat.com.
