At this page you can find some of software myself or other Crocodile Group members wrote. Most of the software here is freeware, for Unix-like operating system, provided with full source code under GPL or BSD licence. Some utilites are just small handy scripts while others are links to a bigger software projects. Substantial part of this software is rather old and have mostly historical value.
All software listed below is free. Few people send me questions, asking how they could thank me for developing it. Best thing you can do is to improve this software and send your modifications back to me. No, I do not want any money contributions. If you really want to send me something, visit my Books Wishlist.
