 <p><em>If you intend to modify the code, use a separate “build” directory: replace</em> “<code>cmake  [ ] .</code>” <em>by</em> “<code>mkdir build ; cd build ; cmake [ ] ..</code>”; <em>you can then clean the build directory with</em> “<code>rm -rf build/*</code>” <em>(run from within the UxPlay source directory) without affecting the source directories which contain your modifications</em>.</p>
 <p>The above script installs the executable file “<code>uxplay</code>” to <code>/usr/local/bin</code>, (and installs a manpage to somewhere like <code>/usr/local/share/man/man1</code> and README files to somewhere like <code>/usr/local/share/doc/uxplay</code>). It can also be found in the build directory after the build processs.</p>
