Building and Running

-Now you can run the following command to get some help about the exact usage:
- $ ./json-rpc-shell --help
+To install the application, you can do either the usual:
+ $ make install
+
+Or you can try telling CMake to make a package for you. For Debian it is:
+ $ cpack -G DEB
+ # dpkg -i json-rpc-shell-*.deb
+
+Note that for versions of CMake before 2.8.9, you need to prefix cpack with
+`fakeroot' or file ownership will end up wrong.
+
+Run the program with `--help' to obtain usage information.
