Move pod2usage.PL, podchecker.PL, podselect.PL into cpan/Pod-Parser/scripts

Let ExtUtils::MakeMaker deal with running these extraction scripts, rather than
repeating the logic in (at least) 5 places.

+
+=item B<-help>
+
+Print a brief help message and exit.
+
+=item B<-man>
+
+Print this command's manual page and exit.
+
+=item B<-exit> I<exitval>
+
+The exit status value to return.
+
+=item B<-output> I<outfile>
+
+The output file to print to. If the special names "-" or ">&1" or ">&STDOUT"
+are used then standard output is used. If ">&2" or ">&STDERR" is used then
+standard error is used.
+
+=item B<-verbose> I<level>
+
+The desired level of verbosity to use:
+
+    1 : print SYNOPSIS only
+    2 : print SYNOPSIS sections and any OPTIONS/ARGUMENTS sections
+    3 : print the entire manpage (similar to running pod2text)
+
+=item B<-pathlist> I<dirlist>
+
+Specifies one or more directories to search for the input file if it
+was not supplied with an absolute path. Each directory path in the given
+list should be separated by a ':' on Unix (';' on MSWin32 and DOS).
+
+=item I<file>
+
+The pathname of a file containing pod documentation to be output in
+usage message format (defaults to standard input).
+
+=back
+
+=head1 DESCRIPTION
+
+B<pod2usage> will read the given input file looking for pod
+documentation and will print the corresponding usage message.
+If no input file is specified then standard input is read.
+
+B<pod2usage> invokes the B<pod2usage()> function in the B<Pod::Usage>
+module. Please see L<Pod::Usage/pod2usage()>.

+=head1 NAME
+
+podchecker - check the syntax of POD format documentation files
+
+=head1 SYNOPSIS
+
+B<podchecker> [B<-help>] [B<-man>] [B<-(no)warnings>] [I<file>S< >...]
+
+=head1 OPTIONS AND ARGUMENTS
+
+=over 8
+
+=item B<-help>
+
+Print a brief help message and exit.
+
+=item B<-man>
+
+Print the manual page and exit.
+
+=item B<-warnings> B<-nowarnings>
+
+Turn on/off printing of warnings. Repeating B<-warnings> increases the
+warning level, i.e. more warnings are printed. Currently increasing to
+level two causes flagging of unescaped "E<lt>,E<gt>" characters.
+
+=item I<file>
+
+The pathname of a POD file to syntax-check (defaults to standard input).
+
+=back
+
+=head1 DESCRIPTION
+
+B<podchecker> will read the given input files looking for POD
+syntax errors in the POD documentation and will print any errors
+it find to STDERR. At the end, it will print a status message
+indicating the number of errors found.
+
+Directories are ignored, an appropriate warning message is printed.
+
+B<podchecker> invokes the B<podchecker()> function exported by B<Pod::Checker>
+Please see L<Pod::Checker/podchecker()> for more details.
+
+=head1 RETURN VALUE
+
+B<podchecker> returns a 0 (zero) exit status if all specified
+POD files are ok.
+
+=head1 ERRORS
+
+B<podchecker> returns the exit status 1 if at least one of
+the given POD files has syntax errors.
+
+The status 2 indicates that at least one of the specified 
+files does not contain I<any> POD commands.
+
+Status 1 overrides status 2. If you want unambiguous
+results, call B<podchecker> with one single argument only.
