# This shell script is used to bootstrap the app and update external libraries
#

# Finish -----------


echo "\n -- clean swap folder --\n"

echo "\n == FINISHED UPDATE == \n"

Always use double quotes. Please add some.

Especially stuff like:

rm -rf $JS_FOLDER/lib/mout

…is potentially dangerous. (What if $JS_FOLDER contains a space?)

I started using Bower for a project, but I didn't like to download the entire repository (docs, tests, README etc), I just wanted the minified and unminified version of the lib.

Maybe this behaviour happened because the lib didn't implement the "component.json" properly, but event if it did, as far as I know, the "component.json" only allow to specify 1 "js" file to be "downloaded".

update: I’ve been using http://volojs.org/ more often instead of the ad-hoc shell scripts, it's flexible enough and let me do basically the same thing.
