help

help has the following syntax:

help [keyword]

Without a keyword, help displays the subcommand set.

With a keyword, help gives helpful information relating to the specified keyword. The keyword may be the first word of any LockLint subcommand. There are also a few other keywords for which help is available:

condvars
locking
example
makefile
ifdef
names
inversions
overview
limitations
shell

If environment variable PAGER is set, that program is used as the pager for help. If PAGER is not set, more is used.
