#
# Options:
# -f : to copy files rather than creating symlinks on the Mac/Linux platforms.
# -d : print make dependencies instead of running make; doesn't copy files.
# -c : copy files expected after make dependencies (reported by -d) have been built.
#
# The purpose of -d/-c is to include the workflow in a make file:
# - the make rule should depend on \$(shell create_all_symlinks -d)
# - the rule body should perform   \$(shell create_all_symlinks -c [-f])
