Its written in Python, its cross platform (though I've only tested it for cygwin and win-2k/XP).
It can perform various mundane tasks related to PBEM hosting.
Please note that it works only if the host has a gmail account!
It can do the following:
1. Retrieve game turn files from gmail (so long as the game's name is in the subject field)
2. Verify that the turns are valid and report invalid ones.
3. Backup (on request and automatically prior to hosting)
4. Restore (reload specific turn from backup)
5. Broadcast messages to players.
6. Send status notifications that include automatically generated report of invalid/missing turns reports to players.
7. Host
8. Distribute turn files to players.
The interface is CLI.
Usage:
1. Install python. whatever platform you're using doesn't matter, the utility doesn't contain platform specific code.
2. Extract the zip file attached, it contains a configuration file and the utility.
3. Dl and install
Libgmail.
Install is usually as simple as extracting the lib then running: python setup.py install.
4. Edit the file .domIII_PBEM_conf for the configuration values. It's a text file that contains explanations.
5. Run domIII_PBEM_utils.py.
6. Follow the CLI instructions.
I already use this utility for hosting, and it saves me plenty of "dirty" work.
