-# The hard-linking for-loop below ensures that there is a bin/ directory
-# full of all of the programs under test (except the ones that are required
-# for basic Makefile rules), all symlinked to the just-built "false" program.
-# This is to ensure that if ever a test neglects to make PATH include
-# the build srcdir, these always-failing programs will run.
-# Otherwise, it is too easy to test the wrong programs.
-# Note that "false" itself is a symlink to true, so it too will malfunction.
+# Use this to make sure we don't run these programs when building
+# from a virgin tgz file, below.
