# 404 replacements for old URLs
# The switch to sphinx caused a few pages to be renamed, sphinx uses
# filename.html whereas doxygen used whatever the @page foo was. So old docs
# *mostly* used underscores, now we're consistent with dashes.
# We can't use htaccess on the server, so let's auto-generate a 404 list
# with a basic page telling users that the link has moved. This can be
# removed in a few months, towards the end of 2018.
#
# File list is: [current-sphinx-input-file, old-generated-page]
# If they're the same they'll be ignored.
