+Linux Infrared Remote Control - use an easy to build home-brewn IR-receiver, an
+(almost) arbitrary remote control and control your Linux box with it! More
+about it at www.lirc.org. Be sure to read LIRC documentation before going ahead
+in this README.
+
+If you have installed the lirc-package, configure will autodetect it. If LIRC
+support is enabled and an error occurs Geeqie will tell you on startup. The
+application name for Geeqie is geeqie. Here is the list of supported commands:
+
+DOWN [int] - Move "camera" down by the specified amount. Default=1
+EXIT - Exit Geeqie
+FIRST - Jump to first image
+INFO - Show image information (full screen only)
+LAST - Jump to last image
+LEFT [int] - Move "camera" left by the specified amount. Default=1
+NEXT - Go to next image
+PAUSE - Pause/unpause slideshow
+PREV - Go to previous image
+RIGHT [int] - Move "camera" right by the specified amount. Default=1
+ROTATE_90 - Rotate image 90 degrees clockwise.
+ROTATE_90_CC - Rotate image 90 degrees counter-clockwise.
+SET_INV_ZOOM [int] - Zoom to 1/Nx. Deafult=1x
+SET_ZOOM [int] - Zoom to Nx. Default=1x
+UP [int] - Move "camera" up by the specified amount. Default=1
+ZOOM_IN [int] - Zoom in. Value specifies the amount of zoom.
+ZOOM_MAX - Zoom to fit image
+ZOOM_OUT [int] - Zoom out. Value specifies the amount of zoom.
+
+Don't forget to enable the repeat flag in .lircrc when it make sense
+(directional buttons, zoom in and out, ...)
+Here's an excerpt from my .lircrc:
+
+begin geeqie
+ begin
+ prog = geeqie
+ button = vol_up
+ config = ZOOM_IN 1
+ repeat = 3
+ end
+ begin
+ prog = geeqie
+ button = vol_down
+ config = ZOOM_OUT 1
+ repeat = 3
+ end
+ begin
+ prog = geeqie
+ button = down
+ config = DOWN 10
+ repeat = 1
+ end
+ begin
+ prog = geeqie
+ button = up
+ config = UP 10
+ repeat = 1
+ end
+ begin
+ prog = geeqie
+ button = right
+ config = RIGHT 10
+ repeat = 1
+ end
+ begin
+ prog = geeqie
+ button = left
+ config = LEFT 10
+ repeat = 1
+ end
+ begin
+ prog = geeqie
+ button = back
+ config = PREV
+ end
+ begin
+ prog = geeqie
+ button = forw
+ config = NEXT
+ end
+ begin
+ prog = geeqie
+ button = skip_back
+ config = FIRST
+ end
+ begin
+ prog = geeqie
+ button = skip_forw
+ config = LAST
+ end
+ begin
+ prog = geeqie
+ button = pause
+ config = PAUSE
+ end
+ begin
+ prog = geeqie
+ button = surround
+ config = SET_ZOOM
+ end
+ begin
+ prog = geeqie
+ button = 1
+ config = ROTATE_90
+ end
+ begin
+ prog = geeqie
+ button = 2
+ config = ROTATE_90_CC
+ end
+ begin
+ prog = geeqie
+ button = 3
+ config = INFO
+ end
+ begin
+ prog = geeqie
+ button = 4
+ config = EXIT
+ end
+end geeqie
+
+At the moment Geeqie uses the standard location for the lirc-config file
+(~/.lircrc).
