# Makefile for Zenoss Javascript files
#
# Approximately 100+ individaul zenoss javascript files are compressed into
# a single 'minified' file using a Sencha tool called JSBuilder. The
# minification process is orchestrated by a json-structured jsb2 build
# file:
#
#                                                +--------------+
# Products/ZenUI3/browser/zenoss.jsb2 ---------->|    sencha    |
# Products/ZenUI3/browser/resources/js/*/*.js -->|   minifier   |-->zenoss-compiled.js
#                                                |--------------|
#                                                |JSBuilder2.jar|
#                                                +--------------+
#
# The jsb2 file defines the output file (e.g. zenoss-compiled.js) and the
# output directory (e.g. resources/js/deploy), so we parse the jsb2 file to
# get those settings.
