[PATCH] document the core-dump-to-a-pipe patch

cd081041 · Matthias Urlichs <[email protected]> · 2006-10-11 01:21:57 -07:00

The pipe-a-coredump-to-a-program feature was undocumented.
*Grumble*.

NB: a good enhancement to that patch would be: save all the stuff that a
core file can get from the %x expansions in the environment.
