If it's run from a terminal, F<perldoc> will usually call F<pod2man> to
translate POD (Plain Old Documentation - see L<perlpod> for an
-explanation) into a man page, and then run F<man> to display it; if

F<man> isn't available, F<pod2text> will be used instead and the output
piped through your favourite pager.

-As well as these two, there are two other converters: F<pod2html> will

F<splain> is an interface to L<perldiag> - paste in your error message

-=head2 CONVERTORS
+=head2 Converters
To help you convert legacy programs to Perl, we've included three
conversion filters:
based around this code:
while (<>) {
- ($Fld1,$Fld2) = split(/[:\n]/, $_, 9999);
+ ($Fld1,$Fld2) = split(/[:\n]/, $_, -1);
print $Fld2;
}
-=item L<s2p|s2p>
+=item L<s2p|s2p> and L<psed>
Similarly, F<s2p> converts F<sed> scripts to Perl programs. F<s2p> run
on C<s/foo/bar> will produce a Perl program based around this:
while (<>) {
- chop;
+ chomp;
s/foo/bar/g;
print if $printit;
}
+When invoked as F<psed>, it behaves as a F<sed> implementation, written in
+Perl.

=item L<find2perl|find2perl>
Finally, F<find2perl> translates C<find> commands to Perl equivalents which
L<pl2pm|pl2pm> utility will help you convert old-style Perl 4 libraries to
new-style Perl5 modules.

+=item L<config_data|config_data>

+Query or change configuration of Perl modules that use Module::Build-based
+configuration files for features and config data.

+=item L<libnetcfg|libnetcfg>
+
+To display and change the libnet configuration run the libnetcfg command.
+
+=item L<perlivp>
+
+The F<perlivp> program is set up at Perl source code build time to test
+the Perl version it was built under. It can be used after running C<make
+install> (or your platform's equivalent procedure) to verify that perl
+and its libraries have been installed correctly.

=head2 Development
There are a set of utilities which help you in developing Perl programs,
please read through the documentation for F<perlbug> thoroughly before
using it to submit a bug report.
+=item L<perlthanks|perlbug>
+
+This program provides an easy way to send a thank-you message back to the
+authors and maintainers of perl. It's just F<perlbug> installed under
+another name.
+
=item L<h2ph|h2ph>
Back before Perl had the XS system for connecting with C libraries,
header files. You may still see C<require 'syscall.ph'> or similar
around - the F<.ph> file should be created by running F<h2ph> on the
corresponding F<.h> file. See the F<h2ph> documentation for more on how
-to convert a whole bunch of header files at ones.

as much glue between C libraries and Perl modules as it can. It's also
very useful for creating skeletons of pure Perl modules.
-=item L<dprofpp|dprofpp>
+=item L<enc2xs>
+
+F<enc2xs> builds a Perl extension for use by Encode from either
+Unicode Character Mapping files (.ucm) or Tcl Encoding Files (.enc).
+Besides being used internally during the build process of the Encode
+module, you can use F<enc2xs> to add your own encoding to perl.
+No knowledge of XS is necessary.
+
+=item L<xsubpp>
+
+F<xsubpp> is a compiler to convert Perl XS code into C code.
+It is typically run by the makefiles created by L<ExtUtils::MakeMaker>.
+
+F<xsubpp> will compile XS code into C code by embedding the constructs
+necessary to let C functions manipulate Perl values and creates the glue
+necessary to let Perl access those functions.
+
+=item L<prove>
+
+F<prove> is a command-line interface to the test-running functionality
+of F<Test::Harness>. It's an alternative to C<make test>.
+
+=item L<corelist>
+
+A command-line front-end to C<Module::CoreList>, to query what modules
+were shipped with given versions of perl.
+

+
+=head2 General tools
+
+A few general-purpose tools are shipped with perl, mostly because they
+came along modules included in the perl distribution.

+
+=item L<piconv>
+
+B<piconv> is a Perl version of B<iconv>, a character encoding converter
+widely available for various Unixen today. This script was primarily a
+technology demonstrator for Perl v5.8.0, but you can use piconv in the
+place of iconv for virtually any case.
+
+=item L<ptar>
+
+F<ptar> is a tar-like program, written in pure Perl.
+
+=item L<ptardiff>
+
+F<ptardiff> is a small utility that produces a diff between an extracted
+archive and an unextracted one. (Note that this utility requires the
+C<Text::Diff> module to function properly; this module isn't distributed
+with perl, but is available from the CPAN.)
+
+=item L<ptargrep>
+
+F<ptargrep> is a utility to apply pattern matching to the contents of files
+in a tar archive.
+
+=item L<shasum>
+
+This utility, that comes with the C<Digest::SHA> module, is used to print
+or verify SHA checksums.
+
+=item L<zipdetails>
+
+L<zipdetails> displays information about the internal record structure of the zip file.
+It is not concerned with displaying any details of the compressed data stored in the zip file.

+These utilities help manage extra Perl modules that don't come with the perl
+distribution.

+
+=item L<cpan>
+
+F<cpan> is a command-line interface to CPAN.pm. It allows you to install
+modules or distributions from CPAN, or just get information about them, and
+a lot more. It is similar to the command line mode of the L<CPAN> module,
-Perl comes with a profiler, the F<Devel::Dprof> module. The
