+=head1 NAME
+
+Class::Accessor::Faster - Even faster, but less expandable, accessors
+
+=head1 SYNOPSIS
+
+  package Foo;
+  use base qw(Class::Accessor::Faster);
+
+=head1 DESCRIPTION
+
+This is a faster but less expandable version of Class::Accessor::Fast.
+
+Class::Accessor's generated accessors require two method calls to accompish
+their task (one for the accessor, another for get() or set()).
+
+Class::Accessor::Fast eliminates calling set()/get() and does the access itself,
+resulting in a somewhat faster accessor.
+
+Class::Accessor::Faster uses an array reference underneath to be faster.
+
+Read the documentation for Class::Accessor for more info.
