.SH NAME
IO \- load various IO modules
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 2
\&   use IO qw(Handle File); # loads IO modules, here IO::Handle, IO::File
\&   use IO;                 # DEPRECATED
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\f(CW\*(C`IO\*(C'\fR provides a simple mechanism to load several of the IO modules
in one go.  The IO modules belonging to the core are:
.PP
.Vb 8
\&      IO::Handle
\&      IO::Seekable
\&      IO::File
\&      IO::Pipe
\&      IO::Socket
\&      IO::Dir
\&      IO::Select
\&      IO::Poll
.Ve
.PP
Some other IO modules don't belong to the perl core but can be loaded
as well if they have been installed from CPAN.  You can discover which
ones exist with this query:  <https://metacpan.org/search?q=IO%3A%3A>.
.PP
For more information on any of these modules, please see its respective
documentation.
.SH DEPRECATED
.IX Header "DEPRECATED"
.Vb 1
\&    use IO;                # loads all the modules listed below
.Ve
.PP
The loaded modules are IO::Handle, IO::Seekable, IO::File, IO::Pipe,
IO::Socket, IO::Dir.  You should instead explicitly import the IO
modules you want.
