%description
"The Faust compiler in a box:" faustgen2~ is a Faust external for Pd
a.k.a. Pure Data, Miller Puckette's interactive multimedia programming
environment. Yann Orlarey's Faust is a functional programming language
developed by Grame, which is tailored for real-time signal processing and
synthesis.

faustgen2~ is based on Pierre Guillot's faustgen~ which in turn was inspired
by Grame's faustgen~ object for Max/MSP. It uses Faust's LLVM-based
just-in-time (JIT) compiler to load, compile and play Faust programs on the
fly. faustgen2~ is an extensive update which offers plenty of new
functionality such as MIDI, polyphony, Scala tunings, OSC, and Pd GUI support,
as well as a Pd loader extension for Faust.

# XXXFIXME: For some reason the compiled binaries don't include any debug
# info, so we need to disable debug packages for now to prevent an error from
# rpmbuild. (While the OBS doesn't build any debug packages anyway, we'd like
# to be able to build them locally at least.)

# Not sure why Fedora's llvm-config prints multiple lines here, fix it.
