This hook script integrates the new fsmonitor capabilities of git with the cross platform Watchman file watching service. To use the script:
Download and install Watchman from https://facebook.github.io/watchman/ and instruct Watchman to watch your working directory for changes ('watchman watch-project /usr/src/git'). Rename the sample integration hook from query-fsmonitor.sample to query-fsmonitor. Configure git to use the extension ('git config core.fsmonitor true') and optionally turn on the untracked cache for optimal performance ('git config core.untrackedcache true').
