# See ../Makefile (included via "include" below) for details.  The main
# differences here are in the directories that we descend into, together with
# new targets for setting up symbolic links in those directories to files in
# their corresponding "standard" directories, under ../.

# WARNING:  This mechanism isn't currently set up to use ACL2(r) automatically.
# When you execute make, be sure to use a command of the form
# make ACL2=your_saved_acl2r

# Before we include the parent directory's Makefile, we add the following to
# make sure soft links have been set up (including some from nonstd Makefiles
# to corresponding standard Makefiles).  It doesn't work to put these at the
# end of this file; they can then be executed too late.
all: links
all-plus: links

# Note that the following assumes that we execute make in this directory.
# Also note that the parent directory provides some directory dependencies
# that may need to be re-thought for the nonstd/ case at some point; but as
# long as things are working, we leave well enough alone.
