+These scripts export the Java-to-C++ translator and the java source files that
+implement the HTML5 parser.  The exported translator may be used (with no
+external dependencies) to translate the exported java source files into Gecko-
+compatible C++.
+
+Hacking the translator itself still requires a working copy of the Java HTML5
+parser repository, but hacking the parser (modifying the Java source files and
+performing the translation) should now be possible using only files committed
+to the mozilla source tree.
+
+Run any of these scripts without arguments to receive usage instructions.
+
+  make-translator-jar.sh: compiles the Java-to-C++ translator into a .jar file
+  export-java-srcs.sh:    exports minimal java source files implementing the
+                          HTML5 parser
+  export-translator.sh:   exports the compiled translator and javaparser.jar
+  export-all.sh:          runs the previous two scripts
+  util.sh:                provides various shell utility functions to the
+                          scripts listed above (does nothing if run directly)
+
+All path arguments may be either absolute or relative.  This includes the path
+to the script itself ($0), so the directory from which you run these scripts
+doesn't matter.
