• Source files should use .go extension.

• workspace is nothing special, but src, bin and pkg (intermediate binary) folders have meaning.

Example structure for an app:

go (workspace)
    bin
    src
    └── github.com
        └── brontosaurusrex
            └── firstapp
                └── Main.go
    pkg
