=head1 NAME

Syntax::Highlight::Engine::Kate::Convert::ToolKit - helper routines,
especially for generating highlight definitions from Kate's originals.

=head1 SYNOPSIS

  use Syntax::Highlight::Engine::Kate::Convert::ToolKit;

  $hlfile = "/some/path/some-lang.xml";
  $toolkit = new Syntax::Highlight::Engine::Kate::Convert::ToolKit();
  # $toolkit->outcmd = sub { ... };  # optionally redefine bare output
  $outfile = $toolkit->register($hlfile);
  $toolkit->pmGenerate($outfile);

=head1 DESCRIPTION

ToolKit module carries helper routines, notably conversion from native
highlight definitions of Kate to the ones as used by
L<Syntax::Highlight::Engine::Kate>.

For convenience, such conversion process is wrapped into provided
L<hl-kate-convert> script.

This module requires L<XML::Dumper> and L<XML::TokeParser> which are not listed
as dependencies of Syntax::Highlight::Engine::Kate.
