+Java support:
+-------------
+
+If GNU gcj is available at build time, two programs will be built as native
+executables:
+      $prefix/lib/gettext/gnu.gettext.*
+and the gettext-tools package will therefore have a runtime dependency to
+libgcj.so.
+
+If GNU gcj is not available at build time but another Java implementation is
+available instead, the two programs will be compiled to Java bytecode only:
+      $prefix/share/gettext/gettext.jar
+and the gettext-tools package will therefore have a runtime dependency to
+the Java virtual machine (Sun Java2, IBM Java2, GNU libgcj.jar, or other).
+
+
+C# support:
+-----------
+
+For C# support, one of pnet or mono must be available at build time; it must
+also be available at run time. If you have both available, choose the desired
+one through the configure option. Note there is no interoperability currently
+between pnet and mono: Programs compiled with pnet don't run with mono, and
+vice versa.
