+                          CS2J Trial Version
+                          ==== ===== =======
+
+This archive contains a trial version of CS2J, a converter that
+translates C# applications into Java applications. It may be used for
+evaluation purposes only.
+
+It has two usage restrictions compared to the full product:
+
+- Java classes are truncated at 150 lines.
+- The XML translation files (under NetFrameworks) are signed.  You can
+  make modifications, or add new translation files, and these will be
+  used by CS2J as long as there are 5 or less translation files
+  without valid signatures. If you hit this limit, then just restore
+  some of the original translation files and try again.
+
+In this directory you will find:
+
+- README: This file.
+- CS2JTranslator: A bin subdirectory contains the cs2j executable and required DLLs.
+- NETFramework: XML translation files for a portion of the .NET Framework.
+- cs2jlib-src-xxxxxxx.zip: CS2JLibrary is a Java source project. The
+  translated Java files will have a dependency on this project. It is
+  licensed under the Apache License 2.0, and so there should be no
+  problem including it in your application.
+- THIRDPARTY-LICENSES: Information about third party software used by CS2J.
+- CS2JUserGuide.pdf: A manual for CS2J. 
+
+We hope you have fun evaluating CS2J.  If you have any questions or
+comments about CS2J just drop us an email.  
+
+If you want to translate your software from C# to Java then please
+contact us for information about our translation services, or about
+licensing CS2J for your own use.
