# Two ways to control which JS engine is used:
# 1. use JS_ENGINE environment variable, value can be either 'jsc' or 'v8'
#    This is the preferred way.
# 2. if JS_ENGINE is not set, or is not 'jsc' or 'v8', this makefile picks
#    up a default engine to build.
#    To help setup buildbot, a new environment variable, USE_ALT_JS_ENGINE,
#    can be set to true, so that two builds can be different but without
#    specifying which JS engine to use.

# Check JS_ENGINE environment variable
