PROGRAM_DESCRIPTION=\
"Patch a target source directory with a series of patches taken
from another directory hierarchy. The idea is that anything that
is found under <patches-dir>/subdir/foo.patch will be applied with
'patch -p1' in <src-dir>/subdir.
Patches are applied in the order they are found by 'find'."
