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