How to ignore files only on one computer

[Carl Youngblood]

I have a situation where I need to change some files in a repository
for my machine but don't want these changes to be passed on to other
developers. I would like to be able to configure my local installation
of bazaar to ignore these files when I do commits. But I can't find
any way of doing this. Git has a global config that can let you set
things like this.

Thanks,
Carl
