This is the directory which contains import packages.
Import packages allow the coder to use shared libraries without linking 
and without requiring the full library::function(...) syntax.

Just include the line :

	import package package-name

at the top of your module, this will read the file from this directory called 
'package-name'


Package file syntax
-------------------

LIBRARY-NAME FUNCTION-NAME

A package may contain functions from more than one library...

eg:

	a4gl_pcre :

		A4GL_pcre pcre_match
		A4GL_pcre pcre_text

Usage :

	import package a4gl_pcre

	main
		if pcre_match("cat|dog","there was a cat") then
			display "Matched to :", pcre_text(1)
		end if
	end main

If you didn't do the import then it would look like :

	main
		if a4gl_pcre::pcre_match("cat|dog","there was a cat") then
			display "Matched to ", a4gl_pcre::pcre_text(1)
		end if
	end main

The package mechanism will later be extended to allow conditional loading, 
something like:

	a4gl_sqllib:ENV(SQLTYPE) sql_connect

The exact syntax and scope has yet to be discussed - but this should allow 
conditional loading of a library module

Take for example :

	a4gl_lang:ENV(A4GL_LANG) get_msg

you could have 

	$ export A4GL_LANG=english
	
and then it would call get_msg in a4gl_lang_english.so

or
	$ export A4GL_LANG=french
	
and then it would call get_msg in a4gl_lang_french.so

This functionality isn't available using the current mechanisms, 
other than by linking the shared library to some common name - but this 
restricts usage to one categeory on one server...

ALL MODULES SHOULD BE shared libraries compiled using 4glpc --as-dll, 
. 
Aubit4GL internal modules should be call libA4GL_<name> (uppercase A4GL lowercase for the rest of the name). User modules should avoid the libA4GL_... prefix so they don't get splatted by a later Aubit4GL module.
