SPINdex
SPINdex is a pair of Perl scripts that allows ones' website to be easily searchable, with minimal overhead and extra programming. SPINdex traverses the directories specified as "search directories", and recursively runs through each of the subdirectories (unless it is flagged as an excluded directory) and checks each file with a suitable extension for the string specified with a case-insensitive regular expression. If the expression matches, the name and URL are recorded.
