Deploy-txp
This is a package to make packaging, deploying, and signing testpilot experiments easier.
It follows the guidelines specified in https://github.com/clouserw/testpilot/blob/7a56f76b4aa2f974c7ea60bfa43ab0a5f9c194db/docs/development/hosting.md
deploy-txp assumes you will have an npm script package which will
run any linting, tests, and package up your addon, leaving it in the
root of your project named addon.xpi.
deploy-txp expects two environment variables, TESTPILOT_AMO_USER,
and TESTPILOT_AMO_SECRET.
