About Watchman - A file watching service

Watchman exists to watch files and record when they change. It can also trigger actions (such as

rebuilding assets) when matching files change.

## Features

* Watchman can recursively watch one or more directory trees (they are called roots)

* Watchman does not follow symlinks. It knows they exist, but they show up the same as any other file in its reporting

* Watchman waits for a root to settle down before it will start to trigger notifications or command execution

* Watchman is conservative, preferring to err on the side of caution; it considers files to be freshly changed when you start to watch them or when it is unsure

* You can query a root for file changes since you last checked, or the current state of the tree

* You can subscribe to file changes that occur in a root
