# Figure out the name of a .egg-info file that might be generated
# as part of the RPM package.  There are two complicating factors.
#
# First, the RPM spec file we generate will just execute "python", not
# necessarily the one in sys.executable.  If *that* version of python has
# a distutils that knows about Python eggs, then setup.py will generate a
# .egg-info file, so we have to execute any distutils logic in a subshell.
#
# Second, we can't just have the subshell check for the existence of the
# distutils.command.install_egg_info module and generate the expected
# file name by hand, the way we used to, because different systems can
# have slightly different .egg-info naming conventions.  (Specifically,
# Ubuntu overrides the default behavior to remove the Python version
# string from the .egg-info file name.)  The right way to do this is to
# actually call into the install_egg_info() class to have it generate
# the expected name for us.
#
# This is all complicated enough that we do it by writing an in-line
# script to a temporary file and then feeding it to a separate invocation
# of "python" to tell us the actual name of the generated .egg-info file.
