lis [-s tab|space] [file ...]The lis utility prints a set of errors to standard error if there are
lines inside each [file ...] that don't use [-s] for indenting.
If [-s] is not specified, the default value is tab. If [file ...]
is absent, lis reads from standard input.
The lis utility exits 0 on success, and `>0` if an error occurs.
