4 ; Modifying this file:
5 ; You should not modify this file except to make bugfixes or
6 ; for other "maintenance". If you want to make custom changes,
7 ; you should create a new datadir subdirectory and copy this file
8 ; into that directory, and then modify that copy. Then use the
9 ; command "rulesetdir <mysubdir>" in the server to have freeciv
10 ; use your new customized file.
