the game; Jason signed on early in the process to help. The assistance
of Peje Nilsson in restructuring some particularly grotty gotos is
-gratefully acknowledged. Petr Voropaev contributed fuzz testing. Aaron

Extreme care has been taken not to make changes that would alter the
logic of the game as we received it from Don Woods, except to fix
glitches that were clearly bugs. By policy, all user-visible
-changes must be revertible with the -o (oldstyle) option.

It is a goal of this project to exactly preserve the *intended
behavior* of 430-point Adventure, but the implementation of it is fair
* Reading the relocated Witt's End sign in the endgame didn't work right.
* Behavior when saying the giant's magic words outside his room wasn't
- quite corrected - the game responded as though the player were in
- the room.
+ quite correct - the game responded as though the player were in
+ the room ("...can't you read?"). The new message is "Well, that was
+ remarkably pointless."
* Attempting to extinguish an unlit urn caused it to lose its oil.
-* Unrecognized words are no longer truncated to 5 characters and
- uppercased when they are echoed.
+* "A crystal bridge now spans the fissure." (progressive present) was
+ incorrect most places it appeared and has been replaced by "A crystal
+ bridge spans the fissure." (timeless present).

+* Under odd circumstances (dropping rug or vase outdoors) the game could

By default, advent issues "> " as a command prompt. This feature
became common in many variants after the original 350-point version,
alias collides with 'd' for 'down', but the others have been implemented.
The "-o" (oldstyle) option disables them.

+Typing a numeric liteteral to the command prompt no longer triggers a
+fatal error. This change is reverted by the oldstyle option.

A "seed" command has been added. This is not intended for human use
but as a way for game logs to set the PRNG (pseudorandom-number generator) so
that random events (dwarf & pirate appearances, the bird's magic word)
checksumming have been discarded - it's pointless to try
tamper-proofing saves when everyone has the source code.
-A -r command-line been added. When it is given (with a file path
-argument) it is functionally equivalent to a RESTORE command.

== Translation ==
Jason Ninneman and I have moved it to what is almost, but not quite,
idiomatic modern C. We refactored the right way, checking correctness
against a comprehensive test suite that we built first and verified
-with coverage tools (we have over 95% coverage, with the remaining
-confined to exception cases that are very difficult to reach). This is
+with coverage tools (there is effectively 100% code coverage). This is
what you are running when you do "make check".
The move to modern C entailed some structural changes. The most
