#!/bin/bash
# Entry point to build the Eclipse plugins for the build server.
#
# Input parameters:
# $1: *Mandatory* destination directory. Must already exist. Cannot contain spaces.
# $2: Optional build number. If present, will be appended to the date qualifier.
#     The build number cannot contain spaces *nor* periods (dashes are ok.)
# -z: Optional, prevents the final zip and leaves the udate-site directory intact.
# -i: Optional, if present, the Google internal update site will be built. Otherwise, 
#     the external site will be built
# Workflow:
# - make dx, ddms, ping
# - create symlinks (for eclipse code reorg, for ddms, ping)
# - call the actual builder script from Brett
# - zip resulting stuff and move to $DEST
# Note: currently wrap around existing shell script, reuse most of it,
# eventually both might merge as needed.

set -e  # Fail this script as soon as a command fails -- fail early, fail fast
