+`libuca` is a thin wrapper to make the different cameras (via !CameraLink or PCIe) accessible in an easy way.

 == Code ==
 
+Followingly, we will build libpco (the hardware-dependent pco.edge "driver") and libuca. First of all, get the sources
+{{{
+#!sh
+cd some-empty-dir
+bzr clone bzr+ssh://user@ufo.kit.edu/vogelgesang/pco-diag libpco
+bzr clone bzr+ssh://user@ufo.kit.edu/vogelgesang/uca libuca
+}}}
+
+Make sure, that you have installed the Silicon Software [http://www.silicon-software.de/download.html Runtime Environment]. Then build and install libpco using
+{{{
+#!sh
+mkdir build && cd build
+cmake ../libpco
+make && sudo make install
+}}}
+If everything went okay, you can try the `diagnose` program in the build directory. It tries to open the camera and frame grabber, prints out some information and stores one frame as `out.raw`.
+
+Finally, you can build libuca
+{{{
+#!sh
+rm -rf *
+cmake ../libuca
+make
+}}}
+
+== Using libuca ==
+
+The following test program is supplied with `libuca` and demonstrates the general functionality of the library:
+
+{{{
+#!c
+#include <stdio.h>
+#include "uca.h"
+
+int main(int argc, char *argv[])
+{
+    struct uca_t *uca = uca_init();
+    if (uca == NULL) {
+        printf("Couldn't find a camera\n");
+        return 1;
+    }
+
+    uint32_t width = 800, height = 600;
+    uca->cam_set_property(uca, UCA_PROP_WIDTH, &width);
+    uca->cam_set_property(uca, UCA_PROP_HEIGHT, &height);
+
+    char camera_name[256] = "foobar";
+    uca->cam_get_property(uca, UCA_PROP_NAME, camera_name);
+
+    printf("Camera name: %s\n", camera_name);
+
+    uca_destroy(uca);
+    return 0;
+}
