-Roughly similar in effect to
+Allows you to both load one or more modules, while setting up inheritance from
+those modules at the same time.  Roughly similar in effect to

+If any of the listed modules are not loaded yet, I<base> silently attempts to
+C<require> them (and silently continues if the C<require> failed).  Whether to
+C<require> a base class module is determined by the absence of a global variable
+$VERSION in the base package.  If $VERSION is not detected even after loading
+it, <base> will define $VERSION in the base package, setting it to the string
+C<-1, set by base.pm>.

 Will also initialize the fields if one of the base classes has it.

+Multiple inheritence of fields is B<NOT> supported, if two or more
 base classes each have inheritable fields the 'base' pragma will
 croak.  See L<fields>, L<public> and L<protected> for a description of
 this feature.
 
-When strict 'vars' is in scope, I<base> also lets you assign to @ISA
-without having to declare @ISA with the 'vars' pragma first.
