Creates a plain-text dump of the tags of each message.
-The output is to the given filename, if any, or to stdout.

These tags are the only data in the notmuch database that can't be

therefore the only critical thing to backup (and much more friendly to

Finally, results can be restricted to only messages within a
particular time range, (based on the Date: header) with a syntax of:
- <intial-timestamp>..<final-timestamp>
+ <initial-timestamp>..<final-timestamp>
Each timestamp is a number representing the number of seconds since
1970\-01\-01 00:00:00 UTC. This is not the most convenient means of
expressing date ranges, but until notmuch is fixed to accept a more
convenient form, one can use the date program to construct
-timestamps. For example, with the bash shell the folowing syntax would
