+# dirs.mk.in

+# This file sets up the installation directories.
+#
+# DO NOT EDIT THIS FILE!

+# 	- dirs.mk is auto-generated from dirs.mk.in by configure.
+#	  If you edit dirs.mk your changes will be spammed.
+#
+#	- Settings in this file may be overriden by giving replacement
+#	  definitions in build.mk.

+# Definition of installation directories, we don't use half of these, but since
+# the configure script has them on offer while passing through, we might as well
+# set them. Note that we have to be careful, because the GNU coding standards
+# have changed a bit over the course of time, and autoconf development reflects
+# this.
+#
+# A little bit of history regarding autoconf and GNU coding standards, use this
+# as a cheat-sheet for the stuff below:
