The intermetrics library utility used to create a new version of the library
file every time a modification was made to it. However now Intermetrics, in
their infinite wisdom have decided to just update the existing version, nice!
However the jerks leave a corrupted library file if CLBR is interrupted,
(ie with control Y).

	So, WARNING do not control Y in the middle of a CLBR operation.
