 DESCRIPTION:
   Java API Compliance Checker (JAPICC) is a tool for checking backward
-  binary/source compatibility of a Java library API. The tool checks classes
+  binary/source compatibility of a Java library API. The tool checks class
   declarations of old and new versions and analyzes changes that may break
-  compatibility: removed class members, added abstract methods, etc. Breakage
-  of the binary compatibility may result in crashing or incorrect behavior of
-  existing clients built with an old version of a library if they run with a
-  new one. Breakage of the source compatibility may result in recompilation
+  compatibility: removed class members, added abstract methods, etc.

   errors with a new library version.
 
-  JAPICC is intended for library developers and operating system maintainers
-  who are interested in ensuring backward compatibility (i.e. allow old clients
