If you are running with either COMPILE_DIR or COMPILE_EXT, you
can do:

  perl -e 'require "compiled_template.tt2"'

and, if it passes, it has no errors.  Here:

  #!/usr/bin/env perl
  #file ttlint

  use Template::Config;

  my %params = (
      COMPILE_DIR => "/tmp",
      ABSOLUTE => 1,
  );  # set these

  my $t = Template::Config->service(\%params);

  # Make sure the version in COMPILE_DIR is current...
  for (@ARGV) {
      # Assumes each element is a full path, or do some fanciness
      # with Cwd and File::Spec to get the full path
      $t->process($_, {});
  }

  # Now require them all
  for (@ARGV) {
      eval {
          require "$_";
      };
      if ($@) {
          warn "$_ had issues: $@\n";
      }
  }

Call it as ./ttlint /path/to/file/1 /path/to/file/2

Tweak to suit.
