+=== Cross Builds

+If you want to build for MS Windows:
+
+  $ sudo aptitude install mingw-w64
+  $ mkdir build
+  $ cd build
+  $ wget -nv http://sourceforge.net/projects/libusbx/files/releases/1.0.11/Windows/libusbx-1.0.11-win.7z

+
+You can run the test program under the http://valgrind.org/[valgrind]
+dynamic analyzer by using a command like:
+
+  $ valgrind --leak-check=full --show-reachable=yes --track-origins=yes \
+    ./bin/picoproj -W 800 -H 480 -f my_image.jpg
