Patch_list Patch

Version:	Version 1.0 (Initial Release)

If you are like me, you probably have several different Circle codebases
running concurrently on your server.  One may be the stock release,
another your current production mud, and one or two others testing some
mew code feature or smippet.  How do you know what one you are running at
any one time?  Any what code have you added to a particular codebase?  I
added this as an extension to the standard "version" command, which for
immortals, will give a list of those patches that have been added.

For example:

Welcome to the land of CircleMUD!  May your visit here be... Interesting.

[ 1204] The Immortal Board Room [ INDOORS ]
   The main hang out of the Gods, the Immortal Board Room is the place to
be.  Gods exchange messages here most every day.  The mortal board room is
to the east and the meeting room for the gods is to the south.  To the north
is the Gods' Inn and to the west is a post office for Gods.  There is a large
staircase leading down to the main temple in the city of Midgaard.  In the
northeast corner you spot a small staircase leading upwards.
[ Exits: n e s w u d ]
A large bulletin board is mounted on a wall here.  It glows with a faint aura.

> version

0: Patch list version 1.0 (2003/06/15)

The code is real simple, only three files are changed.  You can snip the
lines below and feed them friectly into patch if you want.

All you need to do is once you add a patch to code base, add a suitablely
descriptive line to the "patch_list" array in constants.c - before the
final "\n" line of course.  How you format the line is completely up to
you, of course.

Use and enjoy,
