# TODO:
# - install stuff from examples/:
#	- examples/nagios/ + add nagios USE flag etc.
#	  (see also example/reports/check_bacula_pools.sh which is newer

#   - examples/autochangers/
#   - examples/devices/
#   - examples/python/
#   - examples/reports/baculareport.pl
# - correctly filter unneeded /usr/libexec/bacula/ stuff depending
#   on selected USE flags, e.g. bacula-clientonly
# - install bacula-web and/or bweb from bacula-gui package
