+=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>

+
+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.

+=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,
