#The pure part is common to all systems.  
#Object-logics (like FOL) are loaded on top of it.

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

#Environment variable ML_DBASE specifies the initial Poly/ML database, from
#  the Poly/ML distribution directory.
#WARNING: Poly/ML parent databases should not be moved!

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