Should be more portable across different versions of make

#To make the system, cd to this directory and type

#To make the system and test it on standard examples, type  
#	make test
#To generate HTML files for every theory, set the environment variable
#MAKE_HTML or add the parameter "MAKE_HTML=".

#Environment variable ISABELLECOMP specifies the compiler.
#Environment variable ISABELLEBIN specifies the destination directory.
#For Poly/ML, ISABELLEBIN must begin with a /

#Makes pure Isabelle (Pure) if this file is ABSENT -- but not 
#if it is out of date, since this Makefile does not know its dependencies!
