# make clean
2. From the parent directory, rename the FFC directory to something else:
# mv ffc-0.1.0 ffc-0.1.0-mod
3. Unpack the version of FFC that you started from:
# tar zxfv ffc-0.1.0.tar.gz
4. You should now have two FFC directory structures in your current
directory:
# ls
ffc-0.1.0
ffc-0.1.0-mod
5. Now use the diff tool to create the patch:
# diff -u --new-file --recursive ffc-0.1.0
ffc-0.1.0-mod > ffc-<identifier>-<date>.patch
written as one line, where <identifier> is a keyword that can be used
to identify the patch as coming from you (your username, last name,
first name, a nickname etc) and <date> is today’s date in the format
yyyy-mm-dd.
6. The patch now exists as ffc-<identifier>-<date>.patch and can
be distributed to other people who already have ffc-0.1.0 to easily
create your modified version. If the patch is large, compressing it with
for example gzip is advisable:
# gzip ffc-<identifier>-<date>.patch
