+
+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.
