+# 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)]
+#
+# Prompt Expansion Reference:
+# http://www.csse.uwa.edu.au/programming/linux/zsh-doc/zsh_13.html
