/**
 * The Dottydoc API is fairly simple. The tool creates an index by calling:
 * "createIndex" with the same argument list as you would the compiler - e.g:
 *
 * {{{
 * String[] array = {
 *     "-language:Scala2"
 * };
 *
 * Map<String, Package> index = createIndex(array);
 * }}}
 *
 * Once the index has been generated, the tool can also build a documentation
 * API given a Mustache template and a flat resources structure (i.e. absolute
 * paths to each resource, which will be put in the same directory).
 *
 * {{{
 * buildDocs("path/to/output/dir", templateURL, resources, index);
 * }}}
 *
 * The tool can also generate JSON from the created index using "toJson(index)"
 * or directly using "createJsonIndex"
