# https://svn.torproject.org/svn/website/trunk/ to pot files, and
# keep them updated. The script will also convert subdirectories that
# exist in the website module.

# For more information, see the HOWTO and README in
# translation/tools/gsoc09.

# in website/include/versions.wmi. Tags that people usually forget to close,
# as well as tags that are not defined in versions.wmi, have been added.
