+HACKING THE BUILD SYSTEM

+If you change or add to the build system (configure.ac, any Makefile.am,
+etc.), try to check that the following things still work:

+	- out-of-tree builds

+The quagga.net site relies on make dist to work to generate snapshots. It

+included in the dist, or to have a make rule refer to a source file without
