#
# This shell script sets the environment variables JAVA_HOME, ANT_HOME,
# and PATH appropriately for building, testing, and developing
# with this branch of the Flex SDK.
#
# It ensures that the right version of Java and Ant are used
# and that when you invoke a Flex SDK tool such as mxmlc,
# the right copy of that tool is executed.
#
# Usage:
#   cd <some_branch_of_the_Flex_SDK>
#   source setup.sh [-q]
#
# -q will disable any output from the script.
#
# It assumes that Java and Ant are installed at standard locations
# in your system. If you have placed them elsewhere, edit the paths.
#
# Note that you must run this script with the 'source' command.
#
# After running it, you can execute commands such as
#   ant -q main checkintests
# and
#   mxmlc MyApp.mxml
#

# IMPORTANT: If you update this script, be sure to update README.txt
