440 ./tmpl_process3.pl [ I<tmpl_process.pl options> ]
444 This is an alternative version of the tmpl_process.pl script,
445 using standard gettext-style PO files. While there still might
446 be changes made to the way it extracts strings, at this moment
447 it should be stable enough for general use; it is already being
448 used for the Chinese and Polish translations.
450 Currently, the create, update, and install actions have all been
451 reimplemented and seem to work.
459 Translation files in standard Uniforum PO format.
460 All standard tools including all gettext tools,
461 plus PO file editors like kbabel(1) etc.
466 Minor changes in whitespace in source templates
467 do not generally require strings to be re-translated.
471 Able to handle <TMPL_VAR> variables in the templates;
472 <TMPL_VAR> variables are usually extracted in proper context,
473 represented by a short %s placeholder.
477 Able to handle text input and radio button INPUT elements
478 in the templates; these INPUT elements are also usually
479 extracted in proper context,
480 represented by a short %S or %p placeholder.
484 Automatic comments in the generated PO files to provide
485 even more context (line numbers, and the names and types
490 The %I<n>$s (or %I<n>$p, etc.) notation can be used
491 for change the ordering of the variables,
492 if such a reordering is required for correct translation.
496 If a particular <TMPL_VAR> should not appear in the
497 translation, it can be suppressed with the %0.0s notation.
501 Using the PO format also means translators can add their
502 own comments in the translation files, if necessary.
506 Create, update, and install actions are all based on the
507 same scanner module. This ensures that update and install
508 have the same idea of what is a translatable string;
509 attribute names in tags, for example, will not be
510 accidentally translated.
516 Anchors are represented by an <AI<n>> notation.
517 The meaning of this non-standard notation might not be obvious.
519 The create action calls xgettext.pl to do the actual work;
520 the update action calls xgettext.pl and msgmerge(1) to do the
525 xgettext.pl must be present in the current directory; the
526 msgmerge(1) command must also be present in the search path.
527 The script currently does not check carefully whether these
528 dependent commands are present.
530 Locale::PO(3) has a lot of bugs. It can neither parse nor
531 generate GNU PO files properly; a couple of workarounds have
532 been written in TmplTokenizer and more is likely to be needed
533 (e.g., to get rid of the "Strange line" warning for #~).
535 This script may not work in Windows.
537 There are probably some other bugs too, since this has not been
