move config out of Python files; don't make hg-ssh-wrapper a dotfile;
update documentation.

# This file needs to be saved as ~/hg-ssh-wrapper for the user whose ~/.ssh/authorized_keys file
# is rewritten by refresh-auth. It expects to be specified as the target of the "command" section
# in the prefix of a key in the authorized_keys file, and be passed a name associated with an
# ssh key as its only argument. It does some setting up before calling hg-ssh, which does the real
# work of deciding whether to allow the users action based on the type of the action, the key name,
# and the contents of the specified rules file.
# If your repository is laid out differently you may need to modify this file.
set -e
cd repos
# Set up this environment variable - useful for hg hooks to check.
