libgphoto2 — cross-platform digital camera library
#include <gphoto2/gphoto2.h>
The gphoto2
        library provides applications with access to a variety of
        cameras.
This man page will be extended with autogenerated
        documentation of the interface types and methods used for
        communication between the 
        gphoto2 
        library and a frontend.

              gphoto2
              applications may store their configuration used to
              access
              gphoto2.
            
	To track down errors, you can add the
	--debug parameter to the
	gphoto2 command line and, if dealing with
	USB problems, setting the environment variable
	USB_DEBUG=1.
      
CAMLIBS
	      If set, defines the directory where the
	      libgphoto2
	      library looks for its camera drivers (camlibs). You only
	      need to set this on OS/2 systems and broken/test
	      installations.
	    
IOLIBS
	      If set, defines the directory where the
	      libgphoto2_port
	      library looks for its I/O drivers (iolibs). You only
	      need to set this on OS/2 systems and broken/test
	      installations.
	    
LD_DEBUG
	      Set this to all to receive
	      lots of debug information regarding library loading on
	      ld based systems.
	    
USB_DEBUG
	      If set, defines the numeric debug level with which the
	      libusb library 
	      will print messages. In order to get some
	      debug output, set it to 1.
