+synopsis:            A glorified string replacement tool
 description:
     A glorified string replacement tool. For a very specific purpose. That
     purpose being to compile and optimize a static website (or a single-page
     application). Mole inspects source, builds a complete dependency tree,
     minifies and compresses the files, adds fingerprints and writes the result
     to a directory.
