The file upatch200.204 is a shell script for patching release 2.00 and
converting it to release 2.04.  The file upatch204.206 is a similar
patch for converting release 2.04 to 2.06.  And so on.  You will need
to apply only the patch files necessary to get from your starting
point to the current version (2.06):

Starting version:     Apply these patches (in this order):
2.00                   upatch200.204  upatch204.206
2.02                   upatch202.204  upatch204.206
2.04                   upatch204.206

Read the directions at the start of either file.  (Previous UNIX
distributions were versions 2.00, 2.02, and 2.04.)

Files in this directory with names ending in .uu are uuencoded
versions of the same-named files without the .uu .  If you are
downloading by a means that might possibly convert tabs to spaces, or
otherwise mung the patch file (e.g. email or some Web browsers) then
download the uu version ONLY.  You will then need a UNIX-style
uudecode routine to reconstruct the file.  If your machine doesn't
have one (unlikely for a UNIX machine), there is source code available
in the Other-Goodies section of this WWW/gopher/ftp area.  (Sorry, we
can't supply support on compiling uudecode.)
