## CoffeeScript
##
## Coffeescript is transpiled ready for nodejs. This is then moved into
## app so we have the javascript available which other preprocessors may
## expect to exist.
##
## In order to generate the sourcemaps correctly, it seems we have to be
## next to the folder where we want the sources to land, but in order to
## transpile correctly we also need the node_modules for babel and the
## babelrc file. We temporarily move those around.
