The RoL script language recognizes the "typename" of a building, craft, tech, or unit, which is not necessarily the same as the in-game/in-editor name. For example, the Glass Dragon must be referred to as "Glass Dragon Start" instead of "Glass Dragon" in a script file.
The typenames are available in "\Data\[unit, tech, etc.]rules.xml" files. This utility generates a list of typenames and in-game names extracted from those (larger) rules files, intended as reference for script design/coding.
