Utility corner

Tools icon Like most software developers, I'm very happy to spend hours writing a program to do something I could do manually in five minutes. I've started to document and make available some of my efforts, optimistically hoping that somebody else might find them useful, and all the hours lost from my life won't have been completely in vain.

Also like most software developers, I find documentation a chore, so this section of my site isn't growing as rapidly as I hoped it might. If you find any of this stuff useful, consider letting me know, and I might be motivated to do more of it.

All these utilities include source code, and should build cleanly under Cygwin and Linux.
