USE flags

• dbus - Enable dbus support for anything that needs it (gpsd, gnomemeeting, etc)
• debug - Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
• doc - Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
• fam - Enable FAM (File Alteration Monitor) support
