NAME

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

SYNOPSIS

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

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

DESCRIPTION

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

If the module that includes "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.

EXPORT

None by default. The only method is "import", called by "use deprecate;".
