I've come accross some interesting problems people will encounter if they try
to upgrade from 1.3 -> 1.5.(now let me see, 10 I think :-) There are
work arounds but they can slow you down. If you've been following the upgrades
you would not get thses problems.

	- 1.3 rmdir doesn't work under 1.5 . I made rmdir one of the first
	  things to re compile.

	- Lots of the make files have a fancy sed command. Unfortunatly it
	  doesn't work with 1.3 sed. The line as it stands is
		sed <inp >out 'expr1;expr2'
	  a better alternative would be
		sed <inp >out -e 'expr1' -e 'expr2'
	  You can tell that you have the problem by your `make all' commands
	  give a sed error of trailing garbage.

	- As has been noted avoid 1.5.10 tsort, use 1.5.9's version.


Obiviously 1.5ph won't have these problems, as every thing is under the one
system.
