+=head1 NAME
+
+Perl::Critic::Policy::InputOutput::ProhibitJoinedReadline - Use C<local $/ = undef> or L<File::Slurp> instead of joined readline.
+
+=head1 AFFILIATION
+
+This Policy is part of the core L<Perl::Critic> distribution.
+
+
+=head1 DESCRIPTION
+
+It's really easy to slurp a whole filehandle in at once with C<join
+q{}, <$fh>>, but that's inefficient -- Perl goes to the trouble of
+splitting the file into lines only to have that work thrown away.
+
+To save performance, either slurp the filehandle without splitting like so:
+
+  do { local $/ = undef; <$fh> }
+
+or use L<File::Slurp>, which is even faster.
+
+
+=head1 CONFIGURATION
+
+This Policy is not configurable except for the standard options.
+
+
+=head1 CAVEATS
+
+Due to a bug in the current version of PPI (v1.119_03) and earlier,
+the readline operator is often misinterpreted as less-than and
+greater-than operators after a comma.  Therefore, this policy only
+works well on the empty filehandle, C<<>>.  When PPI is fixed, this
+should just start working.
+
+=head1 CREDITS
+
+Initial development of this policy was supported by a grant from the Perl Foundation.
