-----------------------------------------------------------------------------| Algorithm::PermuteInPlace v0.01    - Robin Houston, 2001-08-24-----------------------------------------------------------------------------Note: This version of Algorithm::PermuteInPlace requires Brian Ingerson's      Inline module (available from CPAN) to be installed.NAME       Algorithm::PermuteInPlace - Fast permutationsSYNOPSIS         use Algorithm::PermuteInPlace;         my @array = (1..9);         my $permutor = Algorithm::PermuteInPlace->new(\@array);         print "@array\n";         print "@array\n" while $permutor->next();DESCRIPTION       This module will generate all the permutations of an       array, modifying the array in-place.  That allows it to be       very fast....
