# It seems like per the requests module, we'd like to get the version
# from __init__.py however, __init__.py will import the kerberos
# module.  The kerberos module may not be installed - and when it's
# not, it's pulled in by the requirements.txt.  When it's being
# installed, however, this setup.py is evaluated before the
# kerberos.so module is built and installed, and this bombs.
#
# To fix this, we can use the compiler module to parse __init__.py,
# and as long as __version__ is defined as a constant so that we
# don't have to evaluate it to get the value, we can do some dubious
# groping arond the AST and get the version from that
