+#
+# Wrapper around inotifywait to run tests on file changes.
+# If a test file changes, only this file is run (first), while the whole test
+# suite is run afterwards (and initially).
+#
+# The recommended way to run it is via `make testwatch`, or `make testwatchx`
+# (to exit on first failure).
+#
+# # Internal documentation:
+#   The default run command is "make %s" (where %s gets replaced with the test
+#   file(s)), and can be given as first argument.
+#
+#   You can specify VADER_OPTIONS=-x to exit on the first test failure:
+#       VADER_OPTIONS=-x contrib/run-tests-watch
+#   or use the following:
+#       contrib/run-tests-watch 'make %s VADER_OPTIONS=-x'
+#
+#   VADER_ARGS gets used to focus on a specific test file initially, until
+#   another test file gets changed.
