NAME
    SumLibrary -- compute and check the checksum on a library

SYNOPSIS
    SumLibrary(library)
               A1

    void SumLibrary(struct library *);

FUNCTION
    SumLibrary computes a new checksum on a library.  It can also be
    used to check an old checksum.  If an old checksum does not match,
    and the library has not been marked as changed, then the system
    will call alert().

    This call could also be periodically made by some future
    system-checking task.

INPUTS
    library - a pointer to the library to be changed

NOTE
    An alert will occur if the checksum fails.
