# the purpose of this file is to download
# assigned AngularJS source files and test
# them against this build of AngularMaterial.

# This works by pulling in all of the tags
# form angular.js, finding the highest version
# numbers for each branch (e.g. 1.3 => 1.3.X where
# X is the highest patch release). For each
# detected version it will then copy over each
# of the source files to the node_modules/angular-X
# folder and then run `gulp karma` to see if
# they pass. If there are one or more failed tests
# then this script will propagate a failed exit code

# [INPUT]
# just run `./scripts/test-versions.sh`

# [OUTPUT]
# an exit code of "0" (passing) or "1" (failing)

# [CONFIG VALUES]

# Available Options are: 1.X, 1.X.X, 1.X.X-(beta|rc).X or snapshot
