Comment
From Dragon Age Toolset Wiki
In scripts, comments are denoted by a double slash "//". Anything after a double slash is ignored by the compiler.
#include "rules" //This entire line is a comment. void main() { DoSomethingOrOther(); //The function "DoSomethingOrOther();" will be compiled, but there rest of this line will not be. }
In 2DAs, the special data type "comment" can be used to omit a column from the resource exporter's output.
