Fixed typo.
  Move the generation of the templer script into a
 perl script, for portability.
  Allow --define to set values on the command line.

  For example "--define foo=bar" will define the variable foo
 exactly as if it had been specified within the configuration
 file.
  Document the command-line argument --define.
