-"""Tool for checking if patch contains a regression test.
-
-By default runs against current patch but can be set to use any gerrit review
-as specified by change number (uses 'git review -d').
-
-Idea: take tests from patch to check, and run against code from previous patch.
-If new tests pass, then no regression test, if new tests fails against old code
-then either
-* new tests depend on new code and cannot confirm regression test is valid
-  (false positive)
-* new tests detects the bug being fixed (detect valid regression test)
-Due to the risk of false positives, the results from this need some human
-interpretation.
