# Outline of a TOML-based DSL for configuring hosts. For now, we assume we execute these "on the box".

# Imports are processed first, and given the correct precedence as if they were passed on the command
# line. If an import uses a resolver
imports = [
   "/path/to/local/something.toml",
   "bucket1://some/remote.toml"
]

# Bucket is a resolver type. Configure a bucket called bucket1.

Write Golang!

Go makes writing robust, powerful software easy. Write it!

Prerequesites

• set a GOPATH and all your code lives there (echo $GOPATH)
• make sure Go is installed with go version
• set an alias in your shell to make it easy to hack: alias golang="cd $GOPATH/src/github.com"
