   select = static/**/*.js

   ; Specify options inline
   ;
   [JSHint]

Runs L<jshint|http://www.jshint.com/>, a JavaScript validator, and dies if any
problems were found.

=head1 INSTALLATION

See installation options at L<jshint|http://www.jshint.com/platforms/>. One
easy method is to install L<npm|https://npmjs.org/>, then run

    npm install jshint -g

=head1 CONFIGURATION

This plugin accepts the following configuration options:

=head2 argv

Arguments to pass to C<jshint>.

=head2 cmd

The path for the C<jshint> command. By default this is just C<jshint>, meaning
that the user's C<PATH> will be searched for the command.

=head2 options

A whitespace separated string of options, as L<documented by
jshint|http://www.jshint.com/docs/>. These will be written to a temporary
config file and passed as C<--config> argument.
