ojo - Fun oneliners with Mojo!

=head1 SYNOPSIS

  $ perl -Mojo -E 'say g("mojolicio.us")->dom->at("title")->text'

=head1 DESCRIPTION

A collection of automatically exported functions for fun Perl oneliners. Ten
redirects will be followed by default, you can change this behavior with the
C<MOJO_MAX_REDIRECTS> environment variable.

Proxy detection is enabled by default, but you can disable it with the
C<MOJO_PROXY> environment variable.
