I have an a.pth file in dir_a with a line that says: dir_b In dir_b, I have a b.pth file that lists some eggs in dir_b: JCC-1.9-py2.5-linux-i686.egg lucene-2.3.2-py2.5-linux-i686.egg From http://www.python.org/doc/2.5.2/inst/search-path.html: "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." I assume that .pth files are scanned recursively... is this true? I found an old ticket here: http://bugs.python.org/issue1431, but it wasn't clear how it concludes (ie: do .pth files get scanned recursively for directories to add to the search path or not).

Looks like 1431 was closed by removing a line from the documentation, so it's not surprising that it's not clear.

The docs for 2.7 are a little more clear: http://docs.python.org/install/index.html#inst-search-path says it is not recursive. And looking at the code (http://hg.python.org/cpython/file/086afe7b61f5/Lib/site.py#l184) backs that up.
