-The `.constants.asm` file is used to create a `.constants.sym` file. Typical `.sym` files only list the values of *labels* (ROM banks and addresses); this file is used to list *constants* that are needed by the `.patch.template`. Any constants that the `.patch.template` refers to must be explicitly printed here with the `vc_const` macro.
+The `.constants.asm` file is used to export the values of *constants* that are needed by `.patch.template`. Any constants that the `.patch.template` refers to must be explicitly exported with the `EXPORT` rgbasm directive, so their values may appear in the `.sym`.
