Well I've made a similar tool for domII (and later adopted it for domIII), but it has fallen into disrepair, mainly because of how neatly llamaserver handles PBEM.
Just to get an idea what the tool is about, Its a python CLI that works for Linux and Windows and requires that the host have a gmail account. I've already used it in the past to host dom-II PBEMs.
The game management options look like:
1. Retreive game turns. [into dominions game folder]
2. Send new turns to players. [Distribute new turns]
3. Broadcast a message. [Send a message to all players in active game]
4. Send status notification. [send a notification of which turns are missing to players]
5. Verify that all turns are valid. [print a list of all missing or invalid turns]
6. Backup current turns. [create a backup of the turn files]
7. Reload turns from archive. [reload specific turn from backup]
8. Host game. [verify that all turns are valid, backup and then host the game]
.
Here is
the orginal post (at the bottom of the thread)
I could repair this tool and also add missing features to it and a GUI, actually it would have been nice to do but currently I'm on a tight schedule at work meaning long overtime hours so no time for this. However maybe I could be of some help to this project.
