      For some database types CLSQL has to load external foreign
      libaries.  These are usually searched for in the standard
      locations the operating system uses but you can tell CLSQL to
      look into other directories as well by using the function
      CLSQL:PUSH-LIBRARY-PATH or by directly
      manipulating the special variable
      CLSQL:*FOREIGN-LIBRARY-SEARCH-PATHS*.  If,
      say, the shared library libpq.so needed for PostgreSQL support
      is located in the directory /opt/foo/ on
      your machine you'd use
      
	(clsql:push-library-path "/opt/foo/")
      before loading the CLSQL-POSTGRESQL module. (Note the trailing slash above!) If you want to combine this with fully automatic loading of libraries via ASDF a technique like the following works:
    (defmethod asdf:perform :after ((o asdf:load-op) 
                                    (c (eql (asdf:find-system 'clsql))))
      (funcall (find-symbol (symbol-name '#:push-library-path)
                            (find-package 'clsql))
               #p"/opt/foo/"))
  
      Additionally, site-specific initialization can be done using an
initialization file. If the file /etc/clsql-init.lisp 
exists, this file will be read after the CLSQL ASDF system is loaded.
This file can contain forms to set site-specific paths as well as change
CLSQL default values.
