  12 This script does a first-cut conversion of koha HTML::Template template files (.tmpl).
  13 It creates a mirror of koha-tmpl called koha-tt where converted files will be placed.
  14 By default all files will be converted: use the --file (-f) argument to specify
  15   individual files to process.
  16
  17 Options:
  18     --koharoot (-r): Root directory of koha installation.
  19     --type (-t): template file extenstions to match
  20         (defaults to tmpl|inc|xsl).
  21     --copyall (-c): Also copy across all files in template directory
  22     --file (-f): specify individual files to process
  23     --debug (-d): output more information.
