This chapter describes the asl.library.  The sole purpose of this library
is to provide standard file and font requesters for application programs.

It is easier to understand the asl.library if you are familiar with some
basic concepts of the Amiga operating system, especially tagitem arrays
(described in the "utility library" chapter), intuition screens and
windows, graphics library font structures, and AmigaDOS pattern matching.
