HTDigInstaller is a package installer for the HTDig 3.2.0b6 search engine spider, indexer, and crawler. It streamlines the process of installing and configuring the software.
One of the standout features of this package installer is that it allows you to easily install htdig onto your Mac OS X system, complete with a default database that can be used right away. However, if you plan to index your own pages, you'll need to tweak the configuration file a bit. Luckily, both the ReadMe.rtf file that comes with the installer and Htdig's website have plenty of documentation to help you get started with this.
Overall, I think that anyone looking for a powerful search system that works well with Mac OS X will definitely want to check out htdig and give this package installer a try. It's easy to use, and its default database option makes it a particularly attractive choice for those who want to get up and running quickly.
