# This script imports the W3C Web Performance WG's test suite into WebKit.
#
# You must have checked out the 'webperf' repository from https://dvcs.w3.org/hg/
#
# This script will populate the LayoutTests directory with the new tests. If the
# tests already exist, the script will refuse to run. Please clear out the
# w3c/webperf directory first.
#
# The main step in importing the tests is updating all of the URLs to match our
# directory layout.
