# Python packaging notes:
# 1. Upstream does not yet support python 3, so we build for python 2 only.
# 2. The python build does not link against the library stored in _libdir,
#    because it has to be built differently.  Look for instances of
#    "#ifdef ABC_PYTHON_EMBED ... #endif" in the source code.  Hence, the
#    python2 subpackage is indepedent of the -libs subpackage.

# Upstream doesn't make releases.  We have to check the code out of Mercurial.

%description
ABC is a growing software system for synthesis and verification of
binary sequential logic circuits appearing in synchronous hardware
designs.  ABC combines scalable logic optimization based on And-Inverter
Graphs (AIGs), optimal-delay DAG-based technology mapping for look-up
tables and standard cells, and innovative algorithms for sequential
synthesis and verification.

ABC provides an experimental implementation of these algorithms and a
programming environment for building similar applications.  Future
development will focus on improving the algorithms and making most of
the packages stand-alone.  This will allow the user to customize ABC for
their needs as if it were a toolbox rather than a complete tool.
