long jump botch? I dunno

[PAD Powell]

I have just run into "longjump botch."  I looked through my documentation,
and Bejabbers! there is NOTHING on this.  I looked at longjmp(3), and it
lovingly explained how to use longjmp(), and the tutorial on UNIX gave examples.
But nothing on "botch".

Could somebody (wizard-with-a-heart?) please explain all about the uses/abuses
of LONGJUMP,  which I will lovingly incorporate into the man page, and then
post it to the net?
