dttools is a library of C utilities that I have developed over the course of several projects. You are welcome to use, modify, and enjoy this library within the constraints of the GPL. Sorry, there is no documentation, as this library is simply internal carpentry for larger works.
This library has built on Linux, Solaris, and IRIX in the past.
Your mileage may vary.
To build and install dttools:
tar xvzf dttools-0.9.tar.gz
./configure --prefix /some/where

Questions, comments, and bug fixes may be sent to Douglas Thain.
