.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module is used using \f(CW\*(C`use deprecate;\*(C'\fR (or something that calls
\&\f(CW\*(C`deprecate\->import()\*(C'\fR, for example \f(CW\*(C`use if COND, deprecate;\*(C'\fR).
.PP
If the module that includes \f(CW\*(C`use deprecate\*(C'\fR is located in a core library
directory, a deprecation warning is issued, encouraging the user to use
the version on \s-1CPAN. \s0 If that module is located in a site library, it is
the \s-1CPAN\s0 version, and no warning is issued.
.SS "\s-1EXPORT\s0"
.IX Subsection "EXPORT"
None by default.  The only method is \f(CW\*(C`import\*(C'\fR, called by \f(CW\*(C`use deprecate;\*(C'\fR.
