%description
EPSILON is a powerful OpenSource wavelet image compressor.
Wavelet-driven compressors are know to be much more effective
than traditional DCT-based ones (like JPEG). At the moment,
the program supports 30+ different wavelet filters, runs
in parallel in multi-threaded and MPI environments, can
process HUGE images and much more.

# Single-Variante auch anbieten
# Wenn möglich, Versionen für jeden MPI-Compiler in Fedora. openmpi (f, rh), mpich (rh), mpich2 (f) , mvapich und mvapich2(rh), lam (rh)
# Spezifische Dateien müssen in $MPI_BIN, $MPI_LIB und so
# Binaries brauchen ein Suffix
# Keine ldconfig zulässig!
# Gemeinsames Zeug in -common-Paket das alle benötigen
# Eigene Header-Pakete und Devel-Pakete
#TODO: Options, Doxygen?

#Die Perl-Skripts und man-Pages sind genau gleich. Bins scheinen sich zu unterscheiden. Was ist mit der Bib? Die wird nur einmal gemacht.
