Installing a binary GF distribution:

1. Untar the distribution file:

   $ gtar -zxf GF-2.8-[host].tar.gz

2. Go to the created directory:

   $ cd GF-2.8-[host]

3. Run configure:

   $ ./configure

   If you don't want to install the files under /usr/local, 
   run configure with the right installation prefix. E.g.:

   $ ./configure --prefix=/usr

4. Install:

   $ make install

If the above procedure should fail (e.g. you don't have "make" available), you
can do a manual install:

  1. Untar the package and go to the GF directory, as 1-2 above.

  2. The executable is the file "gf". You may want to move it somewhere
     else, e.g. /usr/local/bin

  3. The libraries are in the subdirectory "lib/". It is recommended to
     create an environment variable GF_LIB_PATH pointing to that directory.
     In the bash shell, you do

     $ export GF_LIB_PATH=[your gf directory]/lib
