1HXCOMM Use DEFHEADING() to define headings in both help text and rST.
2HXCOMM Text between SRST and ERST is copied to the rST version and
3HXCOMM discarded from C version.
4HXCOMM DEF(command, args, callback, arg_string, help) is used to construct
5HXCOMM monitor info commands
6HXCOMM HXCOMM can be used for comments, discarded from both rST and C.
7HXCOMM
8HXCOMM In this file, generally SRST fragments should have two extra
9HXCOMM spaces of indent, so that the documentation list item for "info foo"
10HXCOMM appears inside the documentation list item for the top level
11HXCOMM "info" documentation entry. The exception is the first SRST
12HXCOMM fragment that defines that top level entry.
