+I see you patching and repatching notmuch's CLI to improve it, and I was\r
+wondering whether you had considered actually using `docopt` to generate\r
+the CLI parser from the output.\r
+\r
+It's possible to chain docopts to create a CLI UI very much alike the\r
+git command, and it's more easily maintainable, as you're actually\r
+generating the code from the `--help` page instead of the other way\r
+around, making you focus on how you want the user to use the CLI only.\r
+\r
+Here's the link to the C parser generator:\r
+\r
+    https://github.com/docopt/docopt.c\r
+\r
+it might not be perfect as is, but it could be worth trying out? I\r
+actually never tried the .c version of docopt.\r
+\r
+I had a more extensive experience with the python version, and since\r
+then I totally dropped argparse.\r
+\r
+    https://github.com/docopt/docopt.c\r
+\r
+I even tend to believe that one could create a full CLI using\r
+python+docopt to actually control notmuch using the python notmuch\r
+interface… Even though I'm pretty sure some would yell at me and\r
+want to burn me as an heretic just for suggesting that :-)\r
+\r
+what do you believe?\r
