+HXCOMM Use DEFHEADING() to define headings in both help text and rST.
+HXCOMM Text between SRST and ERST is copied to the rST version and
+HXCOMM discarded from C version.
+HXCOMM DEF(command, args, callback, arg_string, help) is used to construct
+HXCOMM monitor info commands
+HXCOMM HXCOMM can be used for comments, discarded from both rST and C.

+HXCOMM In this file, generally SRST fragments should have two extra
+HXCOMM spaces of indent, so that the documentation list item for "info foo"
+HXCOMM appears inside the documentation list item for the top level
+HXCOMM "info" documentation entry. The exception is the first SRST
+HXCOMM fragment that defines that top level entry.
