# INSTALLDIR and INSTALLDIR_LOCAL is the dir the files will be installed
# in and must be set prior to including this file. INSTALLDIR is used by the
# target "install" and "INSTALLDIR_LOCAL" by the target "all".
#
# The target "all" is made depending on the installed files in
# INSTALLDIR_LOCAL. "install" on the files in INSTALLDIR. Another
# difference is that "all" results in using the variable
# $(INSTALLFILE_LOCAL) to install the files and "install" in using
# $(INSTALLFILE). This allows the difference between linking and actually
# copying (with stripping for bins).
