+  <longdescription>
+    This emulator is capable of providing a faithful replication of the
+    HP48. In order to do so, it requires a copy of the ROM software
+    from YOUR calculator. In order to avoid breaking copyright laws,
+    and upsetting HP, you MUST BE THE PROUD OWNER OF AN HP48 before
+    running this program. Of course you can run this program without a
+    copy of the ROM software in order to write trivial machine code
+    programs but you will not be able to access any of the calculator
+    functionality.
+
+    Instructions on how to download a copy of the ROM are provided
+    later in this document.
