# Easy setup script for populating a user's ~/.hgrc
# This currently does the following:
#   * Load the cadmium extension
#   * Populate the author/email fields to be correct
#   * Alias canonical repositories like onnv-gate
#   * Configures mercurial to use appropriate merge tools
#
# See hgrc(5) for more information
