3HXCOMM This file defines the contents of an array of HMPCommand structs
4HXCOMM which specify the name, behaviour and help text for HMP commands.
5HXCOMM Text between SRST and ERST is rST format documentation.
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.
