# You only need the linker if you're going to make changes to the

# gots your choice; it can run in just about any version of Scheme 48
# or Pseudoscheme.  (It has also been made to run in Scheme->C.)  It
# doesn't matter a whole lot which Scheme you use as long as it's not
# broken or unavailable.  The two best choices are:
# 1. As below: build the linker on the scheme48vm and scheme48.image
#    that are in the current directory.
# 2. LINKER_VM = $(RUNNABLE) $(BIG_HEAP)
#    LINKER_RUNNABLE = $(RUNNABLE)

#    requires you to have squirreled away a previous working version

# Since the distribution comes with a filenames.make, this rule
# shouldn't be invoked for simple installations.  But it will be used
# if you change any of the *-packages.scm files.
#
# You can actually run the forms in filenames.scm in any Scheme
# implementation that has syntax-rules and explicit-renaming low-level
# macros (e.g., most versions of Scheme 48 and Pseudoscheme).
# If there are errors running this script, and you need to debug,
# don't use the initial.image, use something that has a reasonable
# environment.
#
# If this fails and you don't feel like debugging or fixing the problem,
# try "touch filenames.make" and hope for the best.
