In order to create gists you have to get an oauth token. That could be easily
obtained via curl:

    curl -X POST 'https://USERNAME:PASSWORD@api.github.com/authorizations' \
        -d '{"scopes":["gist"],"note":"App::Nopaste"}'

or you can use this module to do the same:

    perl -MApp::Nopaste::Service::Gist -e 'App::Nopaste::Service::Gist->create_token'
