Throughout the course of Node.js's native addon history, addons have ended up being compiled in a variety of different places, depending on which build tool and which version of Node.js was used. In addition, the gyp build tool can produce either a Release or Debug build, each being built into different locations.

This module checks all the possible locations that a native addon would be built at, and returns the first one that loads successfully.

In Debian, addons are always built in the same place - in the Release directory. This module allows upstream code to remain unchanged regardless of the environment it is built in.

Node.js is an event-based server-side JavaScript engine.
