NAME

File::Extension - explain file extensions

SYNOPSIS

  use File::Extension qw(extplain filter_by_meta filter_by_meta_reverse);

  my @filetypes = qw(nes pl pm gb p6);

  for my $what(@filetypes) {
    printf("%s is a %s\n", $what, extplain($what));
  }

The extensions and descriptions are taken from http://fileinfo.com.
