+# custom logic for couchdb json resolution
+# ============================================
+#
+# There are three modes for a node:
+#
+# Multimaster
+# -----------
+#
+#    Multimaster uses bigcouch (soon to use couchdb in replication mode
+#    similar to bigcouch).
+#
+#    Use "multimaster" mode when:
+#
+#     * multiple nodes are marked couch.master
+#     * OR no nodes are marked couch.master
+#
+# Master
+# ------
+#
+#    Master uses plain couchdb that is readable and writable.
+#
+#    Use "master" mode when:
+#
+#     * Exactly one node, this one, is marked as master.
+#
+# Mirror
+# ------
+#
+#    Mirror creates a read-only copy of the database. It uses plain coucdhb
+#    with legacy couchdb replication (http based).
+#
+#    This does not currently work, because http replication can't handle
+#    the number of user databases.
+#
+#    Use "mirror" mode when:
+#
+#     * some nodes are marked couch.master
+#     * AND this node is not a master
