#	* Perl    (e.g. from www.perl.com )
#	* a UNIX-like shell (ouch!)
#
#	I found no fully operational shell and no sources for WIN32 so far,
#	Cygnus' bash e.g. cannot handle this:
#	(echo a>a; echo b>>a)
#	Right now I use the knts that I wrote and simplified scripts.
#	Jeff eliminated many shell-lines in Makefile.*.
#

#	Set this to the UNIX-like shell that you have:
#
#	it is now possible to just use the DOS shell
#
#SHELL=knts

# 	Use std path variables from ms
