Forking 'lockfile' code?

Hi,

I find the functionality of the lockfile part of the procmail package
really useful in a number of scripts that I write.

However, compliling/installing procmail on some of the systems I use
is not a valid option, so I was thinking of forking off the lockfile
code into a project all of it's own.  I am not looking at the moment
to add any functionality, but simply use the (tested!) functionality
you guys have already written.

Not that it really matters, but my thought was to use github.

What I really want to know is am I re-inventing the wheel?  Has this
already been done by someone before? (I've not found any evidence with
my googling.)

Apart from following through with the Artistic licence requirements
and giving a big "thank you" to the devs is there anything else that
you'd like to see in a fork?


Thanks!

Olaf
