# Putting the autoinstall code into webkitpy/thirdparty/__init__.py
# ensures that no autoinstalling occurs until a caller imports from
# webkitpy.thirdparty.  This is useful if the caller wants to configure
# logging prior to executing autoinstall code.

# FIXME: Ideally, a package should be autoinstalled only if the caller
#        attempts to import from that individual package.  This would
#        make autoinstalling lazier than it is currently.  This can
#        perhaps be done using Python's import hooks as the original
#        autoinstall implementation did.

# FIXME: If any of these servers is offline, webkit-patch breaks (and maybe
# other scripts do, too). See <http://webkit.org/b/42080>.
