This is a PHP class that allows you to do unix/linux man page lookups from your website. Easy to use, and produces the results in a nicely formatted layout. It allows you to search with keyword and section numbers, and also display a list of all those found starting with a particular letter, or all starting with digits, or non-alphanumeric characters, etc. This class now includes the ability to cache your results for much faster lookup, and also has a timer built in so that you can guage just how long it takes to display your results.
