=head1 NAME
Pod::Functions - Group Perl's functions a la perlfunc.pod
=head1 SYNOPSIS
use Pod::Functions;
my @misc_ops = @{ $Kinds{ 'Misc' } };
my $misc_dsc = $Type_Description{ 'Misc' };
or
perl /path/to/lib/Pod/Functions.pm
This will print a grouped list of Perl's functions, like the
L<perlfunc/"Perl Functions by Category"> section.
=head1 DESCRIPTION
It exports the following variables:
=over 4
=item %Kinds
This holds a hash-of-lists. Each list contains the functions in the category
the key denotes.
=item %Type
In this hash each key represents a function and the value is the category.
The category can be a comma separated list.
=item %Flavor
In this hash each key represents a function and the value is a short
description of that function.
=item %Type_Description
In this hash each key represents a category of functions and the value is
a short description of that category.
=item @Type_Order
This list of categories is used to produce the same order as the
L<perlfunc/"Perl Functions by Category"> section.
