I got it working to an extend at least,
all the custom values/variables for the config files need to be made.
All the commandline options need to be setup.
After tinkering my alterations tcadmin downloads SE from SteamCMD, installs to the "username"/"server number" folder,
and successfully boots up a server in 64bit mode...
Now i'm just taking care of world/config/environment locations and command line options, if someone has that one down I can combine and upload.
Next step would be making a interactive configuration
(the nice tca form way)
Last step for us would be creating a mod for that gameconfig so you can install server extender MOD API in one go.
(obviously having a form to setup configs, game mods/workshop items and backups etc etc)
ServerExtender allows for a webinterface (rcon style) and commandline worldfolder setting, i'm unsure if the same commandlines work for vanilla executable.
