And here is some code for getting the text out of a PDF, using an excellent little CPAN module called CAM::PDF. (If you don't know how to install CPAN modules, just ask).

This goes through a PDF page-by-page, grabbing the text, and then saves it all to a text file. Note that if your PDF is huge you may want to modify this to do it in chunks (the 367 page PDF I tested it on only took a few seconds, though).

#!/usr/bin/perl                                                       
+                                                          
use warnings;
use strict;
use CAM::PDF;

my $pdf_path = $ARGV[0] or die "No pdf specified";
my $pdf = CAM::PDF->new($pdf_path);

my $text = '';

for my $page (1..$pdf->numPages) {
    $text .= $pdf->getPageText($page);
}

open my $file, '>', 'pdftext.txt';
print $file $text;
close $file;

I'm a peripheral visionary... I can see into the future, but just way off to the side.
