# andynu's theme.
# - svn aware
# - git aware
#   - only branch display
#   - no dirty check (too slow)
# - screen aware (displays window number)
# - displays non-zero exit codes
# - user@host:path in scp friendly format
# - $ for user, # for super.
# - mutes hostname if == $PRIMARY_HOST 
#     (serves to highlight when you have 
#     this prompt on a remote host)
# 
# Example:
# [non-zero exit code]\n
# user@host:path [(git:branch|svn:path)]
