+summary: Experimental map store optimized for small incremental changes
+...
+
+This is an experimental storage driver where changed data is appended.
+Data is simply written as `key = value` pairs to the end of the file.
+This allows changes to individual keys to be written without needing to
+write out the entire object again, but reads would grow gradually larger
+as it still needs to read old overwritten keys. This may be suitable for
+eg rosters where individual contacts are changed at a time. In theory,
+this could also allow rolling back changes.
