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