Several companies offer full-featured regular expression engines. One of the first was Thought, Inc., which developed VanillaSearch. It’s available for trial download and purchase at http://www.thoughtinc.com . More recently, Original Reusable Objects, Inc. has come out with a product called OROMatcher (along with a utility package built using OROMatcher called PerlTools). These products are available for download at http://www.oroinc.com . A binary license to use OROMatcher and PerlTools is being offered absolutely free.
