usage = <<USAGE
Usage: tilt <options> <file>
Process template <file> and write output to stdout. With no <file> or
when <file> is '-', read template from stdin and use the --type option
to determine the template's type.
Options
-l, --list List template engines + file patterns and exit
-t, --type=<pattern> Use this template engine; required if no <file>
-y, --layout=<file> Use <file> as a layout template
-D<name>=<value> Define variable <name> as <value>
-o, --vars=<ruby> Evaluate <ruby> to Hash and use for variables
-h, --help Show this help message
