Autoconf defaults sysconfdir to $prefix/etc. Since default prefix is /usr..=

But config files are installed in $sysconfdir/projectM. So if you run
configure with --prefix=3D/usr and --sysconfdir=3D/etc, then all config
files will be in /etc/projectM, as you'd expect.

Well, instead of running autogen - just run autoreconf. If you change
configure.ac - run autoreconf, if you ammend any of Makefile.am - run
autoreconf, etc... You check out its man page - there is nothing
complicate there.

There is just no need to maintain autogen anymore - autoreconf does this jo=
b.
Rule of thumb - If you've changed anything about autotools - run autoreconf=
 :)
