Usage
 
The help command provides a detailed explanation of the requested topic,
which can be specified by an unambiguous prefix.  The command help ?
produces a terse list of topics for which help is available.  The command
help commands produces a summary of the LP commands.  The command
help lp produces a list of general topics for which help is available.
If you don't get information on the topic you expected after typing a command
like help rewrite, try typing help rewrite- to see if there is
further information about related topics (e.g., rewrite-command or
rewrite-rule).
