- Check ABI/API version
  (http://www.gnu.org/software/libtool/manual/html_node/Libtool-versioning.html)
  * If bumping, bump in:
    * Makefile.am
      - use libtool versioning
    * libconcord.py
      - only need the _current_ part of the version
    * setup.py

- Bump concordance version number
  * concordance/concordance.c
  * concordance/configure.ac
  * libconcord/configure.ac

- Check for old version:
  * fgrep -R '0.20' *

- Make clean, recompile, reinstall, test

- Change version in Changelog, commit

- CVS Export, tar, upload
