# How to build executables.

# The $& notation tells Sequent machines that it can do a parallel make,
# and is harmless otherwise.
# The miniperl -w -MExporter line is a basic cheap test to catch errors
# before make goes on to run preplibrary and then MakeMaker on extensions.
# This is very handy because later errors are often caused by miniperl
# build problems but that's not obvious to the novice.
# The Module used here must not depend on Config or any extensions.

# The seemingly cranky ordering of having $(MINIPERL_EXE) depend on
# lib/buildcustomize.pl despite the reality that lib/buildcustomize.pl needs
# miniperl to exist first permits us to
# a) have one rule generate both miniperl and lib/buildcustomize.pl
#    (so that lib/buildcustomize.pl is always available. This simplifies things)
# b) have the rest of the Makefile depend on the more obvious $(MINIPERL_EXE)
