+# its .o file placed before all others in the command; then

+#
+# for type "choice" typeArgs is a list of possible choices, the first one
+# is the default value. for all other types the typeArgs is the default value
+#
+# a "boolflag" is the type for a flag whose presence or absence, without
+# additional arguments means respectively true or false (default flag type).
