The following changes have been made to this directory since R3:

     o	-shape option added
     o	WM_DELETE_WINDOW support added
     o	bugs fixed

The following changes were made from the R4 release:
     o	added -sound option on SparcStation
     o	overloaded -volume option to also work for sound played
     o	added -soundBindings option to customize sounds for
	different senders and recipients.
     o	Reimplemented the newmsgs function (and the semantics of
	the check_command). Both now return the number of unread
	messages.
     o	Added the review() action

The following changes were made since the first public release:
     o	Updated for SunOS 4.1 (thanks to Greg Earle for the
	patches)
     o	Added the -noMailSound option
     o	Changed the name to xbiff++
     o	Included a couple sounds in the distribution
     o	Various bug fixes
	
	( by Jamie Zawinski <jwz@lucid.com> ):
     o	made it work on non-SparcStations;
     o	added caseSensitive resource to control regexp-matching;
     o	added faceBindings to customize bitmaps for different senders
	and recipients.

     o	Made the sound code work with recent vintages of SunOS

The following changes were made for the 2.0 release:
     o	Added support for AudioFile and HP's proprietary audio server.
     o	Patched with changes made to xbiff from the R4 release to the
	R6 release.
     o	handle multiple-line headers properly
     o	added debug resource to help figure out why regexps aren't working
	the way you think they should.
     o	added quit() action, mostly for tracking memory leaks with Purify.
     o	cleaned up code so it now does header matching only when necessary
	(as opposed to every time xbiff++ woke up).
     o	compiles clean on all architectures supported by the Software
	Warehouse (SunOS 4.1.3, Ultrix 4.2, Solaris 2.3, OSF/1 1.3, OSF/1 3.0,
	and HP-UX 9.*)

The following changes were made for the 2.1 release:
     o	many fixes from Richard Lloyd <R.K.Lloyd@csc.liv.ac.uk>:
	In Imakefile:
	    o added SOUND_DIR and SOUND_PATH variables to the Imakefile.
	    o added a bunch of HP-specific fixes to the Imakefile
	    o added a target in Imakefile to install the sound files in
	      SOUND_DIR
	In SSMailbox.c:
	    o in GetMailFile(), added code to use MAIL envvar if present.
	    o in GetMailFile(), call getpwuid() in preference to getlogin()
	      for username lookup (the latter gives false info if you use
	      "su username")
	    o fixed the Status: line code (which didn't work before)
	In regexp.c:
	    o #include'd <string.h> to get strchr() prototype
     o	Removed the SUNOS4_0_3 definition from Imakefile, since this can be
	determined dynamically.
     o	moved scanmbox() and related routines to scanmbox.c (so it can be
	tested more easily)
     o	moved 'struct SoundStruct' and 'struct MsgStruct' from SSMailbox.c
	to SSMailboxP.h, so it can be shared with scanmbox.c
     o	streamlined GetMailFile(); it's now radically different from the
	version in xbiff, but it's a lot nicer looking.
     o	added a /dev/audio player for HP-UX
     o	all four *play.c files now all use findSoundFile() (and thus use
	either the SOUND_PATH envvar or the statically compiled SOUND_PATH
	definition) to look up sounds
     o	added 'soundPath' option/resource
