+SuiteMappings
+-------------
+
+Optional. List of mappings for the Distribution file in a .changes file, e.g.:
+
+| SuiteMappings
+| {
+| "map stable proposed-updates";
+| "map frozen unstable";
+| "map-unreleased stable unstable";
+| "map-unreleased proposed-updates unstable";
+| "ignore testing";
+| };
+
+There are three mapping types:
+
+(1) map <source> <dest>
+
+ Any target suite of '<source>' is unconditionally overriden to
+ '<dest>'.
+
+(2) map-unreleased <source> <dest>
+
+ Any upload targeted for suite '<source>' will be mapped to
+ '<dest>' iff it contains uploads for an architecture that is not
+ part of '<source>'.
+
+(3) ignore <suite>
+
+ Any target suite of '<suite>' is unconditionally removed from
+ the list of target suites. NB: if the upload had only one
+ target suite this will lead to rejection.
+
+NB: ordering is not guaranteed.
