# == General structure

# Apart from the amf_read and amf_write methods (which distribute the requests
-# from the AMF message), each method generally takes arguments in the order
-# they were sent by the Potlatch SWF. Do not assume typing has been preserved.

# Methods all return an array to the SWF.

# == API 0.6

# == Debugging
-#
+#
# Any method that returns a status code (0 for ok) can also send:
-# return(-1,"message") <-- just puts up a dialogue
-# return(-2,"message") <-- also asks the user to e-mail me
+# return(-1,"message") <-- just puts up a dialogue
+# return(-2,"message") <-- also asks the user to e-mail me
# return(-3,["type",v],id) <-- version conflict
# return(-4,"type",id) <-- object not found
# -5 indicates the method wasn't called (due to a previous error)
-#
+#
# To write to the Rails log, use logger.info("message").
# Remaining issues:
