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.

It periodically checks that a server responds to requests.To use the tool, start the <code>web-server-monitor</code> launcher as follows: </p><blockquote><code>web-server-monitor</code> alert-email host-name [port] [poll-frequency-seconds] [server-response-timeout-seconds]</blockquote><p>The monitor will send a HTTP HEAD request to the server at <code>host-name</code> on port <code>port</code> (or 80) every <code>poll-frequency-seconds</code> seconds (or 1 hour). If the server does not respond within <code>server-response-timeout-seconds</code> (or 75) seconds then the monitor will email <code>alert-email</code> about the problem. Also, if the Web server responds with an error, the monitor will email the error message to <code>alert-email</code>. For example, the following monitors the Web server for the book ``How to Design Programs''</p><blockquote><code>web-server-monitor jay www.htdp.org</code></blockquote><p>On UNIX systems, it is usually a good idea to redirect standard in, out, and error to <code>/dev/null</code> so the monitor will not quit due to a <code>SIGHUP</code> (hangup signal) when you log out. i.e.</p><blockquote><code>web-server-monitor jay www.htdp.org > /dev/null < /dev/null 2>&1 &</code></blockquote><p>Powered by <a href="http://www.plt-scheme.org/"><img width="53" height="19" src="/Defaults/documentation/plt-logo.gif" /></a></p></body></html>
