+You need GCJ to build this.  It was tested with Sun JDK 1.1 and IBM
+JDK 1.1.8 too, after replacing "gcj" with "javac" and "gcjh" with
+"javah" in Makefile.am.  Some combinations of compilation with one
+package and executing using another package (e.g., compile with GCJ,
+run with Sun's JRE) also seemed to work.
+
+$ ./autogen.sh # if building from CVS
+$ ./configure
+$ make
+$ su
+# make install
+# exit
+$ make ExampleIDNA
+$ gij ExampleIDNA räksmörgås

+
+Please let me know if you want to finish and maintain the Java API
+glue.  It may involve some tedious work initially, but could be
+interesting in the long run.
