This directory contains the source code (last1.c) and the man page
(last1.1) for the last1 command that I wrote in order to solve the
constraint on last. The man page describes the command pretty well, so do
take a look at it before starting to use it. Feel free to modify the code
to suit your needs. 

For any more assistance in this regard, mail me at fjohn@ai.uga.edu.
