This is not meant to be comprehensive, a guide, or anything quite that sophisticated, just a couple
notes on what I do at work, in production, and how my environment is set up.

Overview:

- Infrastructure runs on AWS
- We run an internal PaaS based on OpenShift Origin/Kubernetes
- We push code to GitHub, which triggers a webhook, which in turn
  triggers OpenShift to start a build, which fetches the source
  code, and runs the build using the Dockerfile contained in the

###
# A way to know, at runtime, what modules a module has used at compile time.
# In this case, you include `IndirectUsesTracker` into a module. When that module gets
# used in some other module, it makes that module registerable under a namespace of your choosing.
# When the registerable module is used into a third module, that third module will know at runtime which
# registerables were `use`d in it at compile time, via a function titled after the namespace.

• Close Android File Transfer
• Open Activity Monitor and kill “Android File Transfer Agent”
• Go to where you installed “Android File Transfer.app” (I have it under /Applications)
• Ctrl+click –> “Show package contents”
• Go to Contents/Resources
• Rename “Android File Transfer Agent” to e.g. “Android File Transfer Agent_DISABLED”
• Then go to “/Users/username/Library/Application Support/Google/Android File Transfer” and again rename the Agent app.
