+# Revision 1.5 1995/08/10 00:32:19 ceharris
+# Preparation for 3.0b3 beta release:
+# - added code for --kill/--keep, --limit, --protocol, --flush
+# options; --pop2 and --pop3 options now obsoleted by --protocol.
+# - added support for APOP authentication, including --with-APOP
+# argument for configure.
+# - provisional and broken support for RPOP
+# - added buffering to SockGets and SockRead functions.
+# - fixed problem of command-line options not being correctly
+# carried into the merged options record.
+#
+# Revision 1.4 1995/08/09 01:32:41 ceharris
+# Version 3.0 beta 2 release.
+# Added
+# - .poprc functionality
+# - GNU long options
+# - multiple servers on the command line.
+# Fixed
+# - Passwords showing up in ps output.
+#
+# Revision 1.3 1995/08/08 01:01:11 ceharris
+# Added GNU-style long options processing.
+# Fixed password in 'ps' output problem.
+# Fixed various RCS tag blunders.
+# Integrated .poprc parser, lexer, etc into Makefile processing.
