Introducing Drake, a kind of ‘make for data’
It looks like all of the drakefiles could be replaced pretty trivially with Makefiles. Replacing '<-' with ':', ';' with '#', and '$INPUT', '$OUTPUT' with '$<' and '$@', and inserting shell invocations of the Python interpreter looks like it would do the job.<p>The major differences I see are:<p><pre><code>    - Inline support for Python et al.
    - Confirming the steps that will be taken.
    - HDFS support.
</code></pre>
Are there any other big differences?
