Hello, Jim. Thank you very much for your response.
I modified by recipe to use zc.recipe.egg like this: ==== from zc.recipe.egg import Scripts # ... egg = Scripts(buildout, name, options) egg.working_set((distribution_name,)) # ... do_something_useful(distribution_name) ==== But still do_something_useful() is failing (distribution_name is not in sys.path) and I think that's because I didn't use pkg_resources as you suggested. I tried to do it, and read the documentation and source code for pkg_resources, but I was not able to find the functionality I should use. I'll elaborate on what the recipe actually does, just in case: It loads options from an external INI file into the parts section, so other parts can use such variables. To be precise, it loads the variables from a PasteDeploy configuration file. Here's its code (it's just ~30 LOC): http://bitbucket.org/2degrees/deployrecipes/src/tip/deployrecipes.py And here's its documentation: http://packages.python.org/deployrecipes/ The tricky thing is, these files contain an option which is the string representation of a function. I don't need to load the actual function, all I want is to get all those options as strings. But PasteDeploy will always attempt to resolve that option and thus I must make it available. I hope it's not that hard to do with zc.recipe.eggs. Cheers, - Gustavo. On 11/02/10 22:48, Jim Fulton wrote: > The short answer is that buildout doesn't support this.
