But that is not true. If I add a path by setting PYTHONPATH and there is a .pth in that directory then it is read and recursively searched for more .pth files. It is only when the path is added because it is in site-packages that it doesn't load the .pth files found. In http://www.python.org/doc/inst/search-path.html there is more specific language: "The most convenient way is to add a path configuration file to a directory that's already on Python's path, usually to the .../site-packages/ directory. Path configuration files have an extension of .pth, and each line must contain a single path that will be appended to sys.path. (Because the new paths are appended to sys.path, modules in the added directories will not override standard modules. This means you can't use this mechanism for installing fixed versions of standard modules.) "Paths can be absolute or relative, in which case they're relative to the directory containing the .pth file. Any directories added to the search path will be scanned in turn for .pth files. See site module documentation for more information." Directories listed in .pth files in site-packages are "added to the search path" so they should be scanned for more .pth files. This really smells like a bug in either the code or the docs. I hope it is in the code and will eventually be fixed. -- D'Arcy J.M.
