There is a Waterloo C program which references the following header files---

cmslib.h   -and-   depsets.h

the program is called   --   "listtxt.c"
and is located at the website:
http://csg.uwaterloo.ca/sdtp/watcutil/index.html

I do not have a copy of the Waterloo C Development system.
But does anyone know what these two files contain? What they
are used for, etc...? Are there any equivalent Windows or 
Linux header files?
