+# tap3 [DESC] - check output/error/status of a command against a specification
+#
+# A tiny variant of shelltestrunner (format v1), just takes one test
+# case and outputs a TAP line.
+#
+# Input format:
+#
+# CMD
+# <<<
+# INPUT
+# >>>
+# OUTPUT
+# >>> /OUTPUT REGEX/
+# >>>2
+# STDERR
+# >>>2 /STDERR REGEX/
+# >>>= STATUS
+# >>>= !STATUS
+#
+# All but CMD are optional and can be put in any order,
+# Regex variants can be repeated, all patterns must match.
+# By default, STATUS is set to 0 and STDERR assumed empty.
