 # Makefile.am for libatalk/
 
-# rpc should be first because it generates RPC headers included elsewhere
+# This is the version info for the libatalk binary API.  It has three
+# numbers:
+#
+#   Current  -- the number of the binary API that we're implementing
+#   Revision -- which iteration of the implementation of the binary
+#               API are we supplying?
+#   Age      -- How many previous binary API versions do we also
+#               support?
+#
+# To increment a VERSION_INFO (current:revision:age):
+#    If the ABI didn't change:
+#        Return (current:revision+1:age)
+#    If the ABI changed, but it's backward-compatible:
+#        Return (current+1:0:age+1)
+#    If the ABI changed and it isn't backward-compatible:
+#        Return (current+1:0:0)
+#
+# Once an RC is out, DO NOT MAKE ANY ABI-BREAKING CHANGES IN THAT SERIES
+# UNLESS YOU REALLY REALLY HAVE TO.
