Run on your machine

The dependency list of XPathFeed as a web app is provided as cpanfile. You can install required modules by cpanm --installdeps ..

Carton

You can use carton install instead of cpanm --installdeps .. The version of perl on which cpanfile.lock is build is indicated in the .perl-version file. If you use another (different) version of perl, delete cpanfile.lock to avoid troubles with core modules.
