- mkdir -> ${INSTALL_DATA_DIR}
- install docs in share/doc/zebra and the examples in share/examples/zebra
- ${FOO} -> $FOO in DEINSTALL/INSTALL
- better INSTALL script, don't pointlessly install the samples in
share/examples/zebra and then into /etc/zebra as well. tell the end user
that they're installed in share/examples/zebra and let them deal with it.
