+# FAST-Python is a heavy consumer of FAST: its test suite exercises a large part
+# of the FAST utilities -- the CFG builder (FASTTCFGUtility), the local resolver,
+# the SSA transform (FASTCFGTVisitor) and the visitors -- through a real language
+# front-end. Running its tests here catches FAST regressions that FAST's own unit
+# tests do not cover.
+#
+# This mirrors what moosetechnology/Famix does for its FamixCpp and Fortran
+# baselines: load the project under test from the checkout, then load the
+# dependent baseline from GitHub and run only its tests.
