To get my vimrc and use it is easy.
The way I have it is to have the repo be my /home/silas/ so when I need to get it I just change to my home directory and use hg to pull the repo.
hg clone http://bitbucket.org/Silas/vimrc
This will create a vimrc directory and you have to move files over manually.
If I knew a way to just to clone my repo and make it be my home directory that would be great.
