# Some hackery follows.  The program executable needs to have the
# location of the spec file hard-coded into it.  However, we have to
# hard-code the location that the spec file *will* be in when it is
# installed...but we would still like to be able to run the program
# before installing it.  So, the actual executable is named
# .$(PROGRAM_NAME) (notice the leading dot), and $(PROGRAM_NAME) is a
# shell script that calls the executable, specifying the uninstalled
# spec file location via the --spec-file command-line argument.  'make
# install' copies the real executable and spec files into their final
# locations.

# 'make install' target.  This is supplied here so that you can easily

# work because LIBCTL_DIR is not set to the global (post-install)
