Thanks for the response. If I wanted to design my own front end. Is there a way to make changes and not have a dirty version?

I've been searching for this answer and haven't been able to find one.  I also posted this question in the Pool thread, but nobody has responded with an answer.

When looking at someone's p2pool node.  Some of them say Version: 13.4-57-gdfad3cd.  And others will say something like: Version: 13.4-57-gdfad3cd-dirty.  What does the
-dirty represent?  Has code been changed that needs to be verified?

I just want to make sure that if i'm going to mine in a new node that there isn't any funny business.  All I can seem to narrow it down to is certain nodes have custom front ends and those all say dirty. 

Any response would be appreciated.

Thank you

I was looking for a P2Pool node to mine in and I saw that the version ended with -dirty. Can anyone explain to me what that means?  Is it caused by altered code?  It seemed most of the nodes with dirty had customer landing pages. I searched for the answer, but couldn't find any detailed answers.
