The following list represents the modules comprising libgutil.a
Following the list are documented notes for selected modules.
At the present time, those with some sort of "documentation" have a `+' sign to left of their entry,
however ALL modules list what header files they include and what functions are exported.
For quick lookup, there is also an alphabetic listing or a listing-by-file of exported functions.

The janitor wanted to keep it as a single file but was convinced by others that this wood not be fair for people trying to access such a beast across a slow line. So, it now is broken up into this "Table of Contents" entry-point file, accompanied by four files comprising the "Notes" sections of the original single file. The original single file is included for completeness:
