Grunt is not used anymore. Why?
Grunt is realy useful when you want to do some tasks to several files,
like jslint src/**/*.js. But in this case, each files have their own
specific dependencies. For instance, davstorage has jIO, jQuery and Base64,
revisionstorage has jIO and hex_sha256, jio.outro needs hex_md5, etc.
Why use a Makefile?
- All developers know Makefiles
- We can choose a task by typing "make <task>"
- It is more extensible than grunt
- It removes grunt dependency
