 # Allow the user to specify the install program.
+# Note that if the system does not provide a suitable install,
+# configure will use build-aux/install-sh.  Annoyingly, it does
+# not use an absolute path.  So we must take care to always run
+# INSTALL-type commands from the top-level directory.
+# This explains (I think) the cd thisdir seen in several install rules.
