Ignoring some path

[GoogleCodeExporter]

In reality it is not bug but a feature i'd like to use.

A trouble I started to see is how to ignore some directories. For example I 
have some versioned directories by Subversion and Git and these one do not need 
to have its files hardlinked (in my humble opinion). Would implement this 
feature?

BTW: I were writing my own hardlink tool [using bash script] when I found your 
tool. Although my tool works, it is embrionary yet, and need lots of features. 
I thought yours script more interesting and I tending to delete the mine to use 
yours. 

Congrats your beautiful job
