Rails Documentation in CHM Format

Delynn Berry just released another version of the Rails Documentation in CHM format:

CHM format is Microsoft’s proprietary help format for Windows. It allows them to package up an entire Web site of information in a searchable package.

Unfortunately—er—fortunately, I’m on a Mac now. This makes viewing files in CHM format a little tricky. After a quick google search I was able to locate a couple of programs:

• xCHM is nice, but doesn’t display documents using their original stylesheets.
• Chmox allows documents to be displayed with their original stylesheets, yet allows only the viewing of CHM documents, not searching.
• Chamonix happens to handle both search and display admirably, though the UI isn’t as spiffy as Chmox’s.

Are there other options?
