CLSQL uses functions that require 64-bit integer
	parameters and return values. The FFI in most CLSQL
	implementations do not support 64-bit integers. Thus, C helper
	libraries are required to break these 64-bit integers into two compatible
	32-bit integers. The helper libraries reside in the directories
	uffi and db-mysql.
      
	  Files named Makefile.msvc are supplied
	  for building the libraries under Microsoft Windows.  Since
	  Microsoft Windows does not come with that compiler, compiled
	  DLL and LIB library files are
	  supplied with CLSQL.
	
	  Files named Makefile are supplied for
	  building the libraries under UNIX. Loading the
	  .asd files automatically invokes
	  make when necessary. So, manual
	  building of the helper libraries is not necessary on most
	  UNIX systems. However, the location of the MySQL library
	  files and include files may need to adjusted in
	  db-mysql/Makefile on non-Debian
	  systems.
	
	Unzip or untar the UFFI distribution which creates a directory
	for the UFFI files. Add that directory to ASDF's asdf:*central-registry*.
	You can do that by pushing the pathname of the directory onto this variable.
	The following example code assumes the UFFI files reside in the
	/usr/share/lisp/uffi/ 
	directory.
	
(push #P"/usr/share/lisp/uffi/" asdf:*central-registry*)
       If you plan to use the clsql-postgresql-socket interface, you
       must load the md5 module.  Unzip or untar the cl-md5
       distribution, which creates a directory for the cl-md5 files.
       Add that directory to ASDF's
       asdf:*central-registry*.  You can do that by
       pushing the pathname of the directory onto this variable.  The
       following example code assumes the cl-md5 files reside in the
       /usr/share/lisp/cl-md5/ directory.
       
(push #P"/usr/share/lisp/cl-md5/" asdf:*central-registry*)
       
       Unzip or untar the CLSQL distribution which creates a
       directory for the CLSQL files. Add that directory to ASDF's
       asdf:*central-registry*.  You can do that by
       pushing the pathname of the directory onto this variable.  The
       following example code assumes the CLSQL files reside in the
       /usr/share/lisp/clsql/ directory. You need
       to load the clsql system.
	
(push #P"/usr/share/lisp/clsql/" asdf:*central-registry*) (asdf:operate 'asdf:load-op 'clsql) ; main CLSQL package
	The test suite can be executed using the ASDF
	test-op operator. If CLSQL has not been
	loaded with asdf:load-op, the
	asdf:test-op operator will automatically load
	CLSQL. A configuration file named
	.clsql-test.config must be created in
	your home directory. There are instructures on the format of
	that file in the tests/README. After
	creating .clsql-test.config, you can run
	the test suite with ASDF:
	
	  (asdf:operate 'asdf:test-op 'clsql)
