+ABOUT
+
+The main purpose of the Schemacompiler is to automatically generate
+compiler front-ends for different XML dialects. Given an XML schema,
+the schemacompiler will generate an abstract grammar and some aspect
+code for JastAdd, as well as a JavaCC parser description. The
+generated compiler may then be extended with more aspects, and
+possibly new abstract grammar rules, to form a complete compiler.
+
+
+USAGE
+
+$ java GenCompiler [-d dir] [-o outfile] schema
+
+options:
+ -d dir directory where generated files are put.
+ Will be created if not already exists.
+ Default is 'x3d'.
+
+ -o outfile Name for generated grammar files.
+ Default is 'x3d'.
+
+'$ java GenCompiler examples/x3d-3.0.xsd' will generate a compiler for
+x3d in the x3d subdirectory. x3d/build.xml should be studied as an
+example on how to use the generated code.
