Revision history:

v1.0  04-13-94 FJP
      Initial release appears to work at my end.  FTick support not yet
      included, but intended for a future release.  This is also not a
      compiled version.  That will have to wait until some more money
      rolls by for the purposes of buying Rexx Plus.  (Anyone who'd like
      to use a copy of Rexx Plus Compiler in lieu of a postcard is
      certainly allowed to do so!)

v1.1  04-17-94 FJP
      Already found a bug!  The level of a HOST was not being used to
      limit attaches/etc., only queries.  Also added a new feature:
      privelege bits.  Combined with levels, this lets you group your
      echos any way you like, rather than only linearly.

v1.2  05-26-94 FJP
      The previous version's release archive had a file that was about
      one byte wrong, but it was wrong enough that the BITS keyword
      didn't work.  What's worse, a bug (or at very least, a very bizarre
      wart) in ARexx prevented even the real version from working quite
      right.  Both are now fixed.  Many thanks due to Peter Deane, who
      is now both the first and only registered user and the only beta
      tester of this program.

v1.2a 05-29-94 FJP
      Added linking of messages to replies, per a suggestion by Peter
      Deane.  This version is not being released generally, because I
      want to wait until I've done at least one of the two other things
      on my to-do list before I call it a whole new release number.

v1.3  06-26-94 FJP (Internal version, never released)
      Updated a few files in the archive to ensure all the rest works.
      Implemented COUNT command to make startup quicker for people
      with big host files.  Implemented new keyword formats for
      compatability with the GCF; CrystalFix now has its own section
      in GCF files.  Fixed problem with doubled MAIN lines.  Made
      CrystalFix less dependent on Mail: assign or Fido.cfg filename.
      Added CrystalFix LOGFILE command to maintain separate logs;
      also, CrystalFix no longer confused by LOGFILE commands in
      other sections like TrapSched.  Changed the grouping method to
      eliminate the use of bitmasks; not only does this free me from
      fighting the never-ending sequence of bitand() bugs, but it also
      makes it a LOT easier to explain.  Added the ability to rescan
      by creating a temporary config, which avoids dupes being sent
      to all points in an area.  Now supports the continuation
      character \ on the end of lines, though it will not keep them
      when it rewrites the file.

v2.0  07-01-94 FJP
      FTick support; tick areas treated just like message areas,
      except of course they can't be rescanned and there are no pass-
      through areas or request forwarding.  Added aliases RAID and
      ALLFIX to be detected by CrystalFix.  Added HELPFILE command
      thus removing the last dependency on the Mail: assign.  Eliminated
      the reliance on 4D addresses.  Added ADDAREACMD command.  Added
      support for [+] instead of + for people who are very dim.  Added
      the TAGLENGTH and PATHLENGTH commands.  Added support for non-4D
      message headers pretending to be 4D message headers in FidoSetInfo
      and FidoGetInfo.  A compiled C version available to registered users
      in a separate archive.

      Note: to convert from version 1.0-1.2a, you'll need to do some
      work in your Fido.cfg file again.  See Upgrade.readme for more
      info.
