osc.recipe.sysegg 0.1.2

zc buildout recipe to reuse eggs from python site-packages.

This buildout recipe allows you to reuse system wide eggs in your buildout. If SysEggs finds the requested eggs in you pythons site-packages directory (or PYTHONPATH) it will create a .egg-link to it. Other packages that require these eggs will not fetch them.

If force-sysegg is set to any value, the buildout will stop when any required sysegg is not installed.

Example

If you have an application that depends on the python image library (PIL) and you want to use the library that is already installed (e.g. with apt-get on Debian), you can use a buildout.cfg like this:

[buildout]

parts =
    sysegg
    otherpart

[sysegg]
recipe = osc.recipe.sysegg
force-sysegg =
eggs =
  PIL

[otherpart]
recipe = zc.recipe.egg
egg = egg_that_depends_on_PIL

You should list sysegg before all other parts.
