# for example "The Tor Project, Inc"

# A lot of the wml files have custom tags. These tags have been defined
# 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.
# See: https://svn.torproject.org/svn/website/trunk/include/versions.wmi

# We also need to use the nodefault option of po4a; space separated list
# of tags that the module should not try to set by default in any
# category. For now, we only need the input tag.

# If you want to enable this option, set the logfile here.
