1XBill history:
2
30.01 (7/21/94):
4	- Bill moves, and he's in color too.  You can even click on
5		him and he excaims "OUCH!" or "SPLAT!"
6	- window resizing is very wrong
7
80.02 (7/22/94):
9	- program no longer guaranteed to run predictably for
10		longer than nine years (sorry)
11	- ridiculously improved code style (no really a lot!)
12	- added linked list unit and support for multiple monsters
13	- added support for computers
14	- bill says "POW!!!!!!" on button 2
15	- improved Makefile
16	- remembered to include app-defaults file in tar
17
180.03 (7/24/94):
19	- forgot to initialize a variable.  either the stupid aix compiler
20		initialized it anyway or we were really lucky testing it.
21	- removed annoying flicker
22	- has multiple computers on the screen with random OSes
23	- has multiple bills moving on the screen in random directions
24	- used sxpm to create smaller .xpm files, minor savings in memoy
25		and executable size, easier to edit pixmaps
26	- left button (button 1) removes bills from screen
27	- right button (button 3) now resets computers to wingdows.
28
290.04 (7/25/94):
30	- got masking to work (well, maybe not...)
31	- bill now carries the wingdows box around
32	- event handling/speed improved
33
340.1 (7/26/94):
35	- masking really works now
36	- fixed computer pixmap so it looks nice(r)
37	- randomized computer layout now leaves room for bill to stand on right
38	- support for bills walking in, standing at computers and walking out
39	- bills walk towards a specific computer to plunder (primitive ai)
40	- bill turns off computer, 'steals' native os and installs wingdows
41	- count of bills remaining is kept: decreased when bill enters screen
42					  - increased if bill leaves
43	- bill is killable in all states
44	- computer reset to native os on right button
45	- cleaned up code and internal structures
46	- event handling/speed really improved (optimized for the new code)
47	- server lag problems identified
48	- linked list unit fixed so that function to move between lists works
49	- window resizing is still very wrong
50
510.2 (8/14/94)
52	- programmers woke up after being asleep since 7/26.
53	- code structures were fixed very much (again)
54	- bill faces in the direction he's walking
55	- bill explodes in a gory shower of blood when clicked on (yeah!)
56	- bill drops os when killed
57	- the os stays on the ground when bill is killed if it had been stolen
58	- the os bounces up and down while bill carries it
59	- changed default cursor (matias will have to draw a better one later)
60	- cursor changes during drag and drop operation
61	- drag and drop works!  there's a little hack involved, but not
62		too bad...
63	- bill now smart enough to notice that a computer is already
64		corrupted and find a new one
65	- game ends if all computers are lost
66
670.21 (8/15/94)
68	- attempt to port code to athena widgets.  it compiles and
69		runs w/o motif now (i hate C macros) a bit
70	- improved the makefile.  an imakefile one day maybe...
71
720.22 (8/16/94)
73	- when bill leaves the field, he drops the os he's carrying
74	- status bar widget now does something
75
760.3 (8/23/94)
77	- improved responsiveness a lot :)
78	- menubar does something (new game, pause and quit buttons) if
79		motif is used.
80	- levels now exist (barely)
81	- yet more code cleanup
82
830.31 (8/24/94)
84	- a few things depend on the level (freq. and number of appearing
85		bills, number of computers, step size)
86	- bug where a computer is ignored if off is removed
87	- menu code written.
88	- athena code started.  this works more or less, but not too well.
89		i'd recommend using motif and/or a statically linked binary.
90
910.32 (9/18/94)
92	- about box works.  help almost works also.
93	- a bunch of bugs fixed
94	- have an Imakefile now (thanks to Greg Seidman - anthro@cs.umd.edu)
95
960.9 (11/28/94 - a bit busier during school)
97	- warp to arbitrary level works
98	- game pauses when cursor leaves window
99	- cursor warps to near upper left corner of opened dialog boxes
100	- redefined both reset and drag to right button (button 3),
101		added -1 option for people with a one button mouse.
102		-1 may slow the game down a bit.
103	- added -l, -L to specify starting level
104	- added -v for version info
105	- improved pictures a lot
106	- added confirmations for actions
107	- game now pauses well
108	- fixed level difficulty stuff
109	- bill walks at two speeds
110	- minimizes to an icon (a cool one too...)
111	- scoring improved
112	- window cannot be resized now, no matter how hard you try :)
113	- much cooler animations for bill replacing os
114	- added high score list
115	- fixed lots of silly bugs
116	- made program not die from colormap error (i hope)
117
1181.0 (4/5/95-4/9/95)
119	- remembered that the game's not done yet :)
120	- replaced usleep() calls with XtAppAddTimeout().  should make
121		the game more responsive
122	- changed all popup windows to modal dialogs.  cleans up code
123		a lot
124	- removed Athena support, since it would take too long to finish.
125	- made a couple pixmaps a bit smaller
126	- changed colors to gray.  why not?
127	- finally got everything to work with full colormaps
128	- got rid of app-defaults file.  Not really used anyway
129	- Only uses one button now (any button).  Easier to play.
130	- Some Imakefile fixes
131
1321.1 (4/16/95)
133	- modularized widget code, and added Athena widget support (rewritten
134		from scratch).  The game looks better with Motif, but that's
135		not too important.
136	- made pause button only active during game play
137	- warping to a level starts a game if one isn't being played
138	- fixed a potentially nasty bug that could cause bills to get lost
139	- works in TrueColor now (I think - it works in 16 bit mode at least)
140
1411.1a (9/22/95)
142	- fixed bug where getopt() returned a char instead of an int.
143	- fixed bug where hitting Enter when entering a high score
144		corrupted the high score file.
145	- don't fclose() nonexistant files any more.
146	- added BSD as another operating system (patches by Joerg Wunsch,
147		joerg_wunsch@uriah.heep.sax.de)
148	- it was really easy to play forever by guarding one computer.  Now
149		you lose when there's only one computer left running its
150		normal OS.
151	- added man page, written by Pekka Marjola (marjola@trshp.ntc.nokia.com)
152
1532.0 (1/23/1997)
154	- changed around some timer code.
155	- removed Athena DrawingArea widget since CoreWidget works too.
156	- massive code reorganization to improve portability to other
157		GUIs, languages, etc.
158	- Some computers are connected by network cables
159	- When a computer with a network cable becomes infected, it will
160		release a spark down the cable which will infect the
161		computer on the other end.  Pouring the bucket of water
162		on the spark will extinguish it.
163	- Made cursors and various other images look better.
164	- Removed references to defenestration.dorm.umd.edu, which no
165		longer exists.
166	- Added Red Hat logo (fixed broken Red Hat patch).
167	- Added GNU Hurd logo
168	- Added Linux penguin logo
169	- The BSD, Red Hat, Linux, OS/2, and Hurd operating systems are
170		interchangable on the 2 PC computers.
171	- The score is now displayed in the playing field.
172	- Made Athena version far better looking.
173	- Motif version almost completely works with Lesstif.
174
1752.1 (11/15/2001)
176	- converted all code from C++ into C.
177	- cleaned up pretty much all of the code.
178	- modified build system to use GNU autoconf instead of imake.
179	- made the UI system modular, and created modules for the Athena
180	  and Motif widget sets.  By default, both are built into the
181	  binary.
182	- added a GTK front end.
183	- added an option to use a larger playing field.
184	- changed the Athena front end to use Xaw3d when possible.
185	- add Palm OS/CPU (images borrowed from pBill and heavily modified)
