+# This test checks the altmacro string delimiter '<' and '>'.
+# In this test we check the '.noaltmacro' directive.
+# We expect that '.altmacro' and '.noaltmacro' will act as a switch on/off directives to the alternate macro mode.
+# .noaltmacro returns the format into a regular macro handling.
+# The default mode is ".noaltmacro".
