For this particular case shell scripting should be sufficient. And it
should not take too much time. Have a look at the git-submodule.sh
script in the repository. That is the one implementing the git submodule

Additionally you need to extend the documentation and write a test or
two. Writing a test is also done in shell script. The documentation[1] is
in asciidoc which is pretty self explanatory.

The test should probably go into t/t7406-submodule-update.sh and, as
Phil pointed out, in t7403-submodule-sync.sh).

Also make sure to read the shell scripting part in
Documentation/CodingGuidelines and as a general rule: Keep close to the
style you find in the file. And when you are ready to send a patch:

If you are happy but unsure about anything just send a patch with your
implementation (CC me and everyone involved) and we will discuss it here
on the list.

Cheers Heiko
