+GENCLOCKIMG
+
+	genclockimg is a small program to generate clock face PNG images.
+	I made it to generate a time index watermark for my timelapse videos.
+
+	It is written in C and uses cairo and libpopt. These are fairly common
+	and chances are high you already have this installed on your system.
+	
+	I used rahra's cairo_jpg library to handle JPEG images.
+	See https://github.com/rahra/cairo_jpg
+
+BUILDING
+
+	To build genclockimg you need libcairo and libpopt and 
+	their accompanying dev packages installed. You'll also need 
+	a C compiler and GNU Make.
+
+	To build the program:
+
+		make
+
+	To test:
+
+		./genclockimg
+
+	A file 'out.png' should appear.
+
+	To install:
+
+		make install
+		
+	To uninstall:
+	
+		make uninstall
+
+RUNNING
+
+	By default, running the program will create a 128x128 PNG image called 'out.png'
+	in the current directory. The image will contain a simple analog clock indicating
+	the current time.
+
+OPTIONS
+
+	-o filename
+		Output filename. The .png extension is NOT added automaticly!
+		The output is always PNG, even if you name the file differently.
+		
+	-t HH:MM
+		Time to show on the clock
+		
+	-w width
+		Width of the clock image in pixels
+		
+	-h height
+		Height of the clock image in pixels
+		
+	
+EXAMPLES
+
+	Generate a series of clock images based on the timestamps of a series of source images:
+	
+	for file in *.jpg; do genclockimg -t `date -r "${file}" +"%H:%M"` -o "${file}-clock.png"; done
