It is permitted by the GDB license (GNU General Public License) to do
something like the following:

echo "quit" | gdb > foo
tail -2 foo
mail lots,of,people <foo

But a similar situation wouldn't be legal in the case of zope. The zope
license places license restrictions on how you can modify the program's
output independant of the program itself. The GPL only places restrictions
on how you can modify the program itself to produce different output.
