-#
-# Convert Ousterhout format man pages into highly crosslinked
-# hypertext.
-#
-# Along the way detect many unmatched font changes and other odd
-# things.
-#
-# Note well, this program is a hack rather than a piece of software
-# engineering.  In that sense it's probably a good example of things
-# that a scripting language, like Tcl, can do well.  It is offered as
-# an example of how someone might convert a specific set of man pages
-# into hypertext, not as a general solution to the problem.  If you
-# try to use this, you'll be very much on your own.
