This is my dotfiles.  The "setup" script will create the appropriate
symbolic links for dotfiles in $HOME and will create some directories
in $HOME and $HOME/config.  There is a small effort made to avoid
overwriting existing files, but no extensive testing has been
done as this is primarily intended to be run to setup a new account.
If not already set in the environment, you will be prompted
for EMAIL and UNAME, which will be used to set the default
values in git config and in bash startup files.  (We use UNAME
to allow a difference from NAME, which is probably follows
some corporate policy and is not actually your name.)
