=head1 NAME
HTTP::Headers::ActionPack::Util - General Utility module
=head1 VERSION
version 0.09
=head1 SYNOPSIS
use HTTP::Headers::ActionPack::Util;
=head1 DESCRIPTION
This is just a basic utility module used internally by
L<HTTP::Headers::ActionPack>. There are no real user serviceable parts
in here.
=head1 FUNCTIONS
=over 4
=item C<str2time>
This is imported from L<HTTP::Date> and passed on here
for export.
=item C<split_header_words ( $header )>
This will split up a header, respecting all the quoted strings and
such, and return the subject, followed by an array of parameter pairs.
The parameters are returned as an array so that ordering can be
preserved.
=item C<join_header_words ( $subject, @params )>
This will canonicalize the header such that it will add a
space between each semicolon and quote and escape all headers
values appropriately.
