Here is a library of utility routine I have found usefull over the years. Some of the routines are still in a somewhat unstable state, because I can't help fiddling with them (specifically, the parseargs routines are still in flux, both due to obstinate bugs, and my own fickle tastes). You can look at the different manpages for the library: libutils, parseargs, strutils, tables and the README file. You can download the tar file here.
