%description
igraph wants to be an efficient platform for
1) complex network analysis and
2) developing and implementing graph algorithms.
It provides flexible and efficient data structures for graphs and related
tasks. It also provides implementation to many classic and new graph
algorithms like: maximum flows, graph isomorphism, scale-free
networks, community structure finding, etc.

The lib%name-devel package contains the header files and some
documentation needed to develop application with %name.

# Cannot find out the version number of this package; IGRAPH_VERSION is missing.
#
# The official igraph tarballs should contain this file, therefore you are
# most likely trying to compile a development version yourself. The development
# versions need Git to be able to determine the version number of igraph.
#
# It seems like you do have Git but it failed to determine the package version number.
#
# We build from git repository instead tarball.
