require DynaLoader;

=head1 DESCRIPTION
-This specification defines a standard generic interface to the dynamic
+This document defines a standard generic interface to the dynamic
linking mechanisms available on many platforms. Its primary purpose is
to implement automatic dynamic loading of Perl modules.
+This document serves as both a specification for anyone wishing to
+implement the DynaLoader for a new platform and as a guide for
+anyone wishing to use the DynaLoader directly in an application.
+
The DynaLoader is designed to be a very simple high-level
interface that is sufficiently general to cover the requirements
of SunOS, HP-UX, NeXT, Linux, VMS and other platforms.
-It is also hoped that the interface will cover the needs of OS/2,
-NT etc and allow pseudo-dynamic linking (using C<ld -A> at runtime).

+It is also hoped that the interface will cover the needs of OS/2, NT
+etc and also allow pseudo-dynamic linking (using C<ld -A> at runtime).
It must be stressed that the DynaLoader, by itself, is practically
useless for accessing non-Perl libraries because it provides almost no
and "$name".
If any directories are included in @names they are searched before
-@dl_library_path. Directories may be specified as B<-Ldir>. Any other names
-are treated as filenames to be searched for.

To support these systems a dl_expandspec() function can be implemented
either in the F<dl_*.xs> file or code can be added to the autoloadable

appetites about such things as the use of instance variables and the

+methodology. This is not intended as a tutorial for object-oriented
+programming or as a comprehensive guide to Perl's object oriented features,
+nor should it be construed as a style guide.
The Perl motto still holds: There's more than one way to do it.
+=head1 OO SCALING TIPS
+
+=over 5
+
+=item 1
+
+Do not attempt to verify the type of $self. That'll break if the class is
+inherited, when the type of $self is valid but its package isn't what you
+expect. See rule 5.
+
+=item 2
+
+If an object-oriented (OO) or indirect-object (IO) syntax was used, then the
+object is probably the correct type and there's no need to become paranoid
+about it. Perl isn't a paranoid language anyway. If people subvert the OO
+or IO syntax then they probably know what they're doing and you should let
+them do it. See rule 1.
+
+=item 3
+
+Use the two-argument form of bless(). Let a subclass use your constructor.
+See L<INHERITING A CONSTRUCTOR>.
+
+=item 4
+
+The subclass is allowed to know things about its immediate superclass, the
+superclass is allowed to know nothing about a subclass.
+
+=item 5
+
+Don't be trigger happy with inheritance. A "using", "containing", or
+"delegation" relationship (some sort of aggregation, at least) is often more
+appropriate. See L<OBJECT RELATIONSHIPS>, L<USING RELATIONSHIP WITH SDBM>,
+and L<"DELEGATION">.
+
+=item 6
+
+The object is the namespace. Make package globals accessible via the
+object. This will remove the guess work about the symbol's home package.
+See L<CLASS CONTEXT AND THE OBJECT>.
+
+=item 7
+
+IO syntax is certainly less noisy, but it is also prone to ambiguities which
+can cause difficult-to-find bugs. Allow people to use the sure-thing OO
+syntax, even if you don't like it.
+
+=item 8
+
+Do not use function-call syntax on a method. You're going to be bitten
+someday. Someone might move that method into a superclass and your code
+will be broken. On top of that you're feeding the paranoia in rule 2.
+
+=item 9
+
+Don't assume you know the home package of a method. You're making it
+difficult for someone to override that method. See L<THINKING OF CODE REUSE>.
+
