=head1 NAME

deprecate - Perl pragma for deprecating the core version of a module

=head1 SYNOPSIS

use deprecate;	# always deprecate the module in which this occurs

use if $] > 5.010, 'deprecate';	# conditionally deprecate the module

=head1 DESCRIPTION

This module is used using C<use deprecate;> (or something that calls
C<< deprecate->import() >>, for example C<use if COND, deprecate;>).

If the module that includes C<use deprecate> is located in a core library
directory, a deprecation warning is issued, encouraging the user to use
the version on CPAN.  If that module is located in a site library, it is
the CPAN version, and no warning is issued.

=head2 EXPORT

None by default.  The only method is C<import>, called by C<use deprecate;>.

=head1 SEE ALSO

First example to C<use deprecate;> was L<Switch>.
