I have a 145 line Cakefile (http://coffeescript.org/documentation/docs/cake.html) for building our project. It's not all that complex, mostly doing coffescript-compilation, uglifying, compressing scripts and a few tricks when concatenating files. It's a bit old and outdated. So I want this Cakefile converted to a more modern Grup or Grunt file. I will provide the Cakefile and expect the new script with the equivalent functionality.
