# The idea here is to install the epydoc modules in /usr/lib/site-python, so
# they'll be accessible to all Python interpreters. The code below was
# originally based on the postinst for the linda package, but I've now mangled
# it beyond recognition.
#
# Ugh. This is turning out to be rather nasty. Hopefully I have now dealt
# with many of the special cases that users have been reporting.
#
# I originally wanted to compile the packages with the default Python
# interpreter. However, since I depend on various specific versioned python
# packages, this won't work. Users who don't have the default python package
# installed get postinst failures. Instead of using just the default, I look
# for the "best" Python on the machine (starting with the default), and use
# that to compile the modules.
#
# This is not a perfect solution. However, the "best" Python out of my list is
# likely the default, so at least in the general case, users won't have to deal
# with the inefficiency of recompiling the modules every time they run
# Epydoc. I'm open to suggestions as to a better way to do this, given the
# way the Epydoc dependencies are layed out.
#
# I also need to be able to deal with users who have Python alternatives set
# up. In other words, /usr/bin/python might point to /etc/alternatives/python
# and from there to some other strange path. Just because I was able to find
# an interpreter does not mean I have any idea where to find the compileall.py
# script. So, instead of using compileall.py, I just import the underlying
# compileall.compile_dir() function and run it myself with the interpreter I've
# found.
