// Package tool contains abstractions for working with developer
// tools. In particular:
//
// 1) It contains global variables that can be used to store
// attributes of a tool. Automated builds can set these values to
// something meaningful as follows:
//
// go build -ldflags "-X v.io/jiri/tool.<key> <value>" v.io/jiri/<tool>
//
// 2) It provides the Context type, which encapsulates the state and
// abstractions commonly accessed throughout the lifetime of a tool
// invocation.
