+1.3 ->
+	- 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

+	- added test script
+	- added support for exec
+	- removed support for *_POPT_ALIASES env variable -- it was a bad
+	  idea
+	- reorganized into multiple source files

+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 parsting 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.
