An easy way to use asl.library, no need to open asl.library,
unit asl will open it for you.
A lot of overlay functions here.:)
One remark, be aware of that GetMultiFiles use linklist for the
linked list of files, you can't use your own list with ordinary
nodes.
26 Oct 1998
Removed amigaoverlays, use smartlink instead.
05 Nov 2002.
Added the define use_amiga_smartlink.
