Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Renamed my tools directory to "tools". I named it __bgn because I was worried it would clash with a future Pelican updaet. But it seems like this would only happen if I re-ran the quickstart script. "tools" is a better name. :)

bgneal@4 9 Late one night I needed to write some Python code to recursively find empty
bgneal@4 10 directories. Searching online produced some unsatisfactory solutions. Here is
bgneal@4 11 a simple solution that leverages `os.walk`_.
bgneal@4 12
bgneal@4 13 .. sourcecode:: python
bgneal@4 14
bgneal@4 15 import os
bgneal@4 16
bgneal@4 17 empty_dirs = []
bgneal@4 18 for root, dirs, files in os.walk(starting_path):
bgneal@4 19 if not len(dirs) and not len(files):
bgneal@4 20 empty_dirs.append(root)
bgneal@4 21
bgneal@4 22 If you then wish to delete these empty directories:
bgneal@4 23
bgneal@4 24 .. sourcecode:: python
bgneal@4 25
bgneal@4 26 for path in empty_dirs:
bgneal@4 27 os.removedirs(path)
bgneal@4 28
bgneal@4 29 .. _os.walk: http://docs.python.org/2/library/os.html#os.walk
