# Build a target for JavaScript files.  The find command excludes directories
# as needed through the -prune directive, and the grep command removes
# individual unwanted JavaScript and JSON files from the list.
# find(1) is used here to build a list of JavaScript targets rather than bzr
# due to the speed of network access being unpredictable (bzr accesses the
# parent branch, which may be lp:juju-gui, for any command relating to the
# branch or checkout).  Additionally, working with the release or an export,
# a developer may not be working in a bzr repository.

# creates the directory, and directories are a bit tricky with Makefiles so we
# are OK with that.  The ULTIMATE_VERSION is used here because we always want
# the version.js file to reflect the top-most entry in the CHANGES.yaml file,
# regardless of whether we are doing a "Stable" or "Development" release.
