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.
