To combat this, a 'guildtree' command was added to the mud.
To use this command you type guildtree 'alpha guild here'. For example 'guildtree fighter' would produce a table containing all the guilds in the fighter tree, sorted by guild level with their pre-requisites.
The output of this command leaves something to be desired, however it is fully automated and is not reliant on a wizard updating the file by hand. The tree is rebuilt at every reboot.
The guild trees are also available on the web page by clicking on the guilds link.
