static USAGE_STRING: &'static str = r#"Tools for jsparagus + SmooshMonkey development
USAGE:
cargo run --bin smoosh_tools [COMMAND] [OPTIONS]
COMMAND:
build [--opt] [MOZILLA_CENTRAL]
Build SpiderMonkey JS shell with SmooshMonkey enabled, using this
jsparagus clone instead of vendored one
shell [--opt] [MOZILLA_CENTRAL]
Run SpiderMonkey JS shell binary built by "build" command
test [--opt] [MOZILLA_CENTRAL]
Run jstests/jit-test with SpiderMonkey JS shell binary built by
"build" command
bench [--opt] [--samples-dir=REAL_JS_SAMPLES/DATE] [MOZILLA_CENTRAL]
Compare SpiderMonkey parser performance against SmooshMonkey on a
collection of JavaScript files, using the JS shell binary built by
"build" command.
bump [MOZILLA_CENTRAL]
Bump jsparagus version referred by mozilla-central to the latest
"ci_generated" branch HEAD, and re-vendor jsparagus
try [--remote=REMOTE] [MOZILLA_CENTRAL]
Push to try with current jsparagus branch
This pushes current jsparagus branch to "generated" branch, and
modifies the reference in mozilla-central to it, and pushes to try
This requires L1 Commit Access for hg.mozilla.org,
and mozilla-central should be a Git repository
gen [--remote=REMOTE]
Push current jsparagus branch to "generated" branch, with generated
files included, to refer from mozilla-central
OPTIONS:
MOZILLA_CENTRAL Path to mozilla-central or mozilla-unified clone
This can be omitted if mozilla-central or mozilla-unified
is placed next to jsparagus clone directory
--opt Use optimized build configuration, instead of debug build
--remote=REMOTE The name of remote to push the generated branch to
Defaults to "origin"
--concat-mozconfig For building mozilla-central, concatenates the content
of the MOZCONFIG environment variable with the content of
smoosh_tools mozconfig.
--samples-dir=DIR Directory containing thousands of JavaScripts to be used
for measuring the performance of SmooshMonkey.
