+Hi,\r
+\r
+for what it's worth, you can simulate a post-tag hook in a somewhat ugly\r
+way by putting a script called "notmuch" in front of the notmuch binary\r
+in your PATH. The script can then call the original notmuch binary as\r
+usual, inspect the first argument, and, if it's "tag", invoke your\r
+script afterwards. I.e. something like this:\r
+\r
+-------------------------------------\r
+#!/bin/sh\r
+\r
+/usr/bin/notmuch $@\r
+retval=$?\r
+if [[ "$1" == "tag" ]]; then\r
+   shift 1\r
+   your-script $@\r
+fi\r
+exit $retval\r
+-------------------------------------\r
+\r
+On a more general note, I'm experimenting with a way to synchronize tags\r
+by logging and replaying tag commands performed on other machines and\r
+for such an approach a post-tag hook would help. It seems to me that not\r
+all use cases for a post-tag hook can be handled as nicely with mtimes.\r
+\r
+Best regards,\r
+Daniel\r
