%description
B::Deobfuscate is a backend module for the Perl compiler that generates
perl source code, based on the internal compiled structure that perl itself
creates after parsing a program. It adds symbol renaming functions to the
B::Deparse module. An obfuscated program is already parsed and interpreted
correctly by the B::Deparse program. Unfortunately, if the obfuscation
involved variable renaming then the resulting program also has obfuscated
symbols.

This module takes the last step and fixes names like $z5223ed336 to be a
word from a dictionary. While the name still isn't meaningful it is at
least easier to distinguish and read. Here are two examples - one from
B::Deparse and one from B::Deobfuscate.

Initial input

  if(@z6a703c020a){(my($z5a5fa8125d,$zcc158ad3e0)=File::Temp::tempfile(
  'UNLINK',1));print($z5a5fa8125d "=over 8\n\n");(print($z5a5fa8125d
  @z6a703c020a)or die(((("Can't print $zcc158ad3e0: $!"))); print($z5a5fa8125d
  "=back\n");(close(*$z5a5fa8125d)or die(((("Can't close ".*$za5fa8125d.": $!")
  ));(@z8374cc586e=$zcc158ad3e0);($z9e5935eea4=1);}

After B::Deparse:

  if (@z6a703c020a) {
      (my($z5a5fa8125d, $zcc158ad3e0) = File::Temp::tempfile('UNLINK', 1));
      print($z5a5fa8125d "=over 8\n\n");
      (print($z5a5fa8125d @z6a703c020a)
          or die((((q[Can't print ] . $zcc158ad3e0) . ': ') . $!)));
      print($z5a5fa8125d "=back\n");
      (close(*$z5a5fa8125d)
          or die((((q[Can't close ] . *$za5fa8125d) . ': ' . $!)));
      (@z8374cc586e = $zcc158ad3e0);
      ($z9e5935eea4 = 1);
  }

After B::Deobfuscate:

  if (@parenthesises) {
      (my($scrupulousity, $postprocesser) = File::Temp::tempfile('UNLINK', 1));
      print($scrupulousity "=over 8\n\n");
      (print($scrupulousity @parenthesises)
          or die((((q[Can't print ] . $postprocesser) . ': ') . $!)));
      print($scrupulousity "=back\n");
      (close(*$scrupulousity)
          or die((((q[Can't close ] . *$postprocesser) . ': ') . $!)));
      (@interruptable = $postprocesser);
      ($propagandaist = 1);
  }

You'll note that the only real difference is that instead of variable names
like $z9e5935eea4 you get $propagandist.
