/**
 * NOTE: Run in a project root that already has a remote configured
 *
 * # v0.5.0 (this is the npm default version)
 *
 * `npm install nodegit@^v0.5.0`
 *
 * NOTE: DOES_NOT fetch from S3 (see also https://github.com/nodegit/nodegit/issues/736)
 *
 * Try 1 - Trying with `remote.initCallbacks(callbacks)` -  api doc states it should be this
 *  * FAIL: Error: remote.initCallbacks is undefined
 *
 * Try 2 - Trying with `remote.setCallbacks(callbacks)` - this is the old method; so expected failure
 *  * FAIL: Error: remote.setCallbacks is undefined
 *
 * Try 3 - Trying with `remote.connect(opt, callbacks)`
 *  * FAIL: Error: Must call UPLOADPACK_LS before UPLOADPACK
 *
 * # v0.4.1
 * `npm install nodegit@^v0.4.1`
 *
 * NOTE: DOES fetch from S3
 *
 * Try 1 - Trying with `remote.initCallbacks(callbacks)` -  api doc states it should be this
 *  * FAIL: Error: remote.initCallbacks is undefined
 *
 * Try 2 - Trying with `remote.setCallbacks(callbacks)` - this is the old, undocumented, method; that works on 0.4.1
 *  * SUCCESS
