+;; antlr3 is partially written using antlr3 grammar files. It also depends on
+;; ST4 (stringtemplate4), which is also partially written using antlr3 grammar
+;; files and uses antlr3 at runtime. The latest version requires a recent version
+;; of antlr3 at runtime.
+;; Fortunately, ST4 4.0.6 can be built with an older antlr3, and we use antlr3.3.
+;; This version of ST4 is sufficient for the latest antlr3.
+;; We use ST4 4.0.6 to build a boostrap antlr3 (latest version), and build
+;; the latest ST4 with it. Then we build our final antlr3 that will be linked
+;; against the latest ST4.
+;; antlr3.3 still depends on antlr3 to generate some files, so we use an
+;; even older version, antlr3.1, to generate them. Fortunately antlr3.1 uses
+;; only grammar files with the antlr2 syntax.
+;; So we build antlr3.1 -> antlr3.3 -> ST4.0.6 -> antlr3-bootstrap -> ST4 -> antlr3.
