Why does GuideMaker refuse to compile my mixin?

GuideMaker requires that the <mixin> command be the first GuideScript command in the first source file compiled. (This will usually be the first file listed in your "Main" or "Build" file.) If you put the <mixin> command anywhere else - even elsewhere in the first source file - GuideMaker won't compile the mixin.

GuideMaker can work with a maximum of nine mixins at a time. If you're compiling a guide with many mixins, and they are located in the same folder as your compiled guide file, you may need to move some of the mixins while compiling or testing with GuideMaker.
