CLOSURE=/tmp/closure
mkdir $CLOSURE || die cannot make $CLOSURE does it already exist?

cd $CLOSURE || die cannot cd to $CLOSURE after making it.  that is really unexpected.  good luck.
git clone "https://github.com/google/closure-library.git" || die cannot clone upstream repo
cd closure-library || die cannot cd to closure-library after cloning it.  did they rename it?

CLOSURE_VERSION=`cat package.json  |grep version |head -1 |sed 's/^.*": "//' |sed 's/".*//'`
prompt version is ${CLOSURE_VERSION}.  hopefully this looks sane to you.

SHA1=`git log --format=%H -1`
prompt sha1 of head is ${SHA1}.  hopefully this looks sane to you.

tar cvf - . |(cd $CHROMIUM && tar xvf - ) || die cannot tar.  or untar.  or maybe cd.  im a script, not a door.

cd $CHROMIUM || die cannot cd to $CHROMIUM after copying new library
