+source-check
+------------
+
+Source-checks are tasks that look at the Gecko source directly to check
+correctness.  This can include linting, Python unit tests, source-code
+analysis, or measurement work -- basically anything that does not require a

 -----
 
 Test tasks for Gecko products are divided into several kinds, but share a
 common implementation.  The process goes like this, based on a set of YAML
 files named in ``kind.yml``:
 
  * For each build task, determine the related test platforms based on the build
