The syntax for angel-commands is:
'@cmd:' starts and angel-command. The identifier is
the the string to type on console to invoke the command. It can have
any value, but should not interfere with regular commands.
After the identifier there is an optional comment that is shown instead of the commands when the option 'hide commands' (x) is on. If the comment is missing, 'hide commands' has no effect.
'@cmdend' at the end of line marks the end of the angel-command.
