+dnl For each whitespace-separated version token in to-check, check if we can
+dnl run the programs automake-VER and aclocal-VER.  The special token 'default'
+dnl also checks the unversioned automake and aclocal (or, if set in the
+dnl environment, $AUTOMAKE and $ACLOCAL).
+dnl
+dnl Then test-action is expanded such that shell variables $ac and $am refer to
+dnl the aclocal and automake programs, and $amver is the actual version
+dnl reported by --version.  The action should do nothing if the version is
+dnl acceptable, or "continue" if the version is unacceptable.
+dnl
+dnl If an acceptable version is found, the AUTOMAKE and ACLOCAL environment
+dnl variables are set accordingly.  Otherwise, the test group is skipped.
