+written as a single small C tool with no dependencies.  This makes it
+well-suited to embedded and other systems without a C++ compiler, or for use in
+applications such as software installers that need only to decompress files,
+not compress them.
+Lunzip is intended to be fully compatible with the regular lzip package.")
