+! This is a simple driver file with information used by make.com to
+! check if external libraries (like t1lib and freetype) are available on
+! the system.
+!
+! Layout of the file:
+!
+!    - Lines starting with ! are treated as comments
+!    - Elements in a data line are separated by # signs
+!    - The elements need to be listed in the following order
+!      1.) Name of the Library 
+!      2.) Location where the object library can be found
+!      3.) Location where the include files for the library can be found
+!      4.) Include file used to verify library location
+!      5.) CPP define to pass to the build to indicate availability of
+!          the library
+!
+! Example: The following  lines show how definitions
+!          might look like. They are site specific and the locations of the
+!          library and include files need almost certainly to be changed.
+!
+! Location: All of the libaries can be found at the following addresses
+!
+!   ZLIB:     http://www.decus.de:8080/www/vms/sw/zlib.htmlx
