# Remove the reference PNG files from the cairo source tarball.
# These are used only for build time testing, and cairo always fails
# a large number of tests, making these files more or less useless to
# the average end user.  If you really need them for some reason, you
# can fetch the original tarball from cairographics.org.
#
# Removing these files reduces the size of the source tarball by 93%.
