The "patch" command - at least, GNU patch as recommended by the
INSTALL docs - knows how to determine the filename from the contents
of the bbd-background.patch file. If you look at this file, it begins
with

diff -urN src-bb19e/dohostsvc.c src/dohostsvc.c
--- src-bb19e/dohostsvc.c       2004-01-02 22:08:44.000000000 +0100
+++ src/dohostsvc.c     2004-01-26 11:11:37.944637264 +0100

which tells the patch-utility to modify the file "src/dohostsvc.c".

(The "-p" option can be used to strip off directory elements from
that filename, but since the recommended method is to use "-p0",
that will not happen).

The man-page for GNU patch also shows this way of running the patch
utility:


NAME
       patch - apply a diff file to an original

SYNOPSIS
       patch [options] [originalfile [patchfile]]

       but usually just

       patch -pnum <patchfile

Henrik
