# TMPDIR is where the tmp files get stored, usually /tmp or /tmp/jove.  If
# your system does not remove subdirectories of /tmp on reboot (lots do
# remove them these days) then it makes sense to make TMPDIR be /tmp/jove.
# But if you want to recover buffers on system crashes, you should create a
# directory that doesn't get clearned upon reboot, and use that instead.
# You would probably want to clean out that directory periodically with
# ``cron''.  LIBDIR is for online documentation, the PORTSRV process,
# RECOVER, and the system-wide .joverc file.  BINDIR is where to put the
# executables JOVE and TEACHJOVE.  MANDIR is where the manual pages go for
# JOVE, RECOVER and TEACHJOVE.  MANEXT is the extension for the man pages,
# e.g., jove.1 or jove.l or jove.m.
