Subject: Add a (half)-functional comment field
X-Git-Url: https://git.cworth.org/git?p=zombocom-ai;a=commitdiff_plain;h=252a783ab361e62990e31e5cbf483663548a34be

Add a (half)-functional comment field

This sends the comment from the client to the server (but not back again).

The server process simply prints the comment out on its console.
