If and when these files change, do that.
"ifn" is a contraction of "iffen" which is a contraction of "if and when". The
module ifn is a CLI tool to help you execute scripts whenever certain files
change.
npm install -g ifn
ifn [options] <pattern1> <pattern2> ... pattern <executable>
Some examples:
# Run on-change.bat whenever a js file in scripts/ changes
ifn scripts/**/*.js on-change.bat
# Run "grunt build" whenever a src script or style changes
ifn src/**/*.js src/**/*.css "grunt build"
# Have lots of things changing rapidly? Debounce!
ifn --debounce 300 dir/** "node run-updates.js"
