servo/tests/wpt/web-platform-tests/css/tools/README.md

This directory contains the CSS build system.

It is recommended that it is run with ../build-css-testsuites.sh, as this ensures all dependencies are installed. Note that it is not required to build the testsuites to run tests; you can just run tests as with any other web-platform-tests tests (see ../../docs/).

The build system is formed of build.py in this directory, the w3ctestlib package in w3ctestlib/, and the apiclient package in apiclient/apiclient/. Note that apiclient exists as a separate upstream project at https://hg.csswg.org/dev/apiclient/, and that ideally any changes here should make it upstream.
