Rosegarden is an attractive, user-friendly MIDI and audio sequencer, notation editor, and general-purpose music composition and editing application for Unix and Linux. The only documented hard dependency of Rosegarden is fftw, so it *must* be installed. Jack-audio-connection-kit is documented as an optional dependency, but testing here indicates that it must also be installed. liblo, liblrdf, and ladspa are optional dependencies; they will be used if they are available at build time. LIRC is another optional dependency; if you want lirc-support, you will have to pass LIRC=yes to the script. All dependencies (required and optional) are available at SlackBuilds.org.
