+dumpbit:
+-------
+        Dumpbit its a simple program wich takes a .bit file generated by
+        Xilinx tools and dumps the binary stream in a file.
+
+bit2svf:
+-------
+        This program is used for generate a SVF file with the needed
+        sequence for store the contents of a Xilinx .bit file inside some
+        PROM or FPGA.
+
+Working mode:
+             A template file with instructions for generate the svf file is
+             used. A different template is used for each different algorithm.
+               The format specification can be found in a README file inside
+             the "templates/" dir wich also has two samples.
+
+bitinfo:
+-------
+        This program was written by Sullins [davesullins@earthlink.net] and is
+        used for read the header of the Xilinx bit files.
+        Its internally used by bit2svf and dumpbit.
+        The full distribution with its documentation can be found inside the
+        bitinfo-3.0 directory.
+
+jbit:
+----
+     This script, using bit2svf, generates a temporal SVF file for the
+     specified device with the specified bit file and then uses the program
+     JTAG for transfering it this file. When finish it erases the temp file.
+     It was created for simplify the process of programming a Xilinx device
+     with GPL tools.
