Little Helper contains a full text search engine.
Currently it indexes all html-files in /collects/doc.
A mockup web-interface is present in order to facilitate easy experimentation with searches.
Run run-indexer to generate the index for your documentation dir.
Run launch to start a web-server with the search interface.
Note: Currently assumes w3m is in your path (used to precompute the
preview-snippets shown in the search results.
