Note that for now, the text document must be saved before
bbjshint can check it.
Use from BBEdit's Scripts menu by either installing or symlinking
bbjshint to BBEdit's Scripts folder. This is
~/Library/Application Support/BBEdit/Scripts or perhaps
~/Dropbox/Application Support/BBEdit/Scripts. You can show this folder from BBEdit by going to the scripts menu and choosing "Open Scripts Folder".
npm install --global bbjshint cd ~/Library/Application\ Support/BBEdit/Scripts ln -s `which bbjshint`
