NAME

       Template::Tools::tpage - Process templates from command line

USAGE

	   tpage [ --define var=value ] file(s)

DESCRIPTION

       The tpage script is a simple wrapper around the Template Toolkit processor.  Files specified by name on the command line are processed in
       turn by the template processor and the resulting output is sent to STDOUT and can be redirected accordingly.  e.g.

	   tpage myfile > myfile.out
	   tpage header myfile footer > myfile.html

       If no file names are specified on the command line then tpage will read STDIN for input.

       The "--define" option can be used to set the values of template variables.  e.g.

	   tpage --define author="Andy Wardley" skeleton.pm > MyModule.pm

       See Template for general information about the Perl Template Toolkit and the template language and features.
