425 ./tmpl_process3.pl [ I<tmpl_process.pl options> ]
429 This is an alternative version of the tmpl_process.pl script,
430 using standard gettext-style PO files. While there still might
431 be changes made to the way it extracts strings, at this moment
432 it should be stable enough for general use; it is already being
433 used for the Chinese and Polish translations.
435 Currently, the create, update, and install actions have all been
436 reimplemented and seem to work.
444 Translation files in standard Uniforum PO format.
445 All standard tools including all gettext tools,
446 plus PO file editors like kbabel(1) etc.
451 Minor changes in whitespace in source templates
452 do not generally require strings to be re-translated.
456 Able to handle <TMPL_VAR> variables in the templates;
457 <TMPL_VAR> variables are usually extracted in proper context,
458 represented by a short %s placeholder.
462 Able to handle text input and radio button INPUT elements
463 in the templates; these INPUT elements are also usually
464 extracted in proper context,
465 represented by a short %S or %p placeholder.
469 Automatic comments in the generated PO files to provide
470 even more context (line numbers, and the names and types
475 The %I<n>$s (or %I<n>$p, etc.) notation can be used
476 for change the ordering of the variables,
477 if such a reordering is required for correct translation.
481 If a particular <TMPL_VAR> should not appear in the
482 translation, it can be suppressed with the %0.0s notation.
486 Using the PO format also means translators can add their
487 own comments in the translation files, if necessary.
491 Create, update, and install actions are all based on the
492 same scanner module. This ensures that update and install
493 have the same idea of what is a translatable string;
494 attribute names in tags, for example, will not be
495 accidentally translated.
501 Anchors are represented by an <AI<n>> notation.
502 The meaning of this non-standard notation might not be obvious.
504 The create action calls xgettext.pl to do the actual work;
505 the update action calls xgettext.pl and msgmerge(1) to do the
510 xgettext.pl must be present in the current directory; the
511 msgmerge(1) command must also be present in the search path.
512 The script currently does not check carefully whether these
513 dependent commands are present.
515 Locale::PO(3) has a lot of bugs. It can neither parse nor
516 generate GNU PO files properly; a couple of workarounds have
517 been written in TmplTokenizer and more is likely to be needed
518 (e.g., to get rid of the "Strange line" warning for #~).
520 This script may not work in Windows.
522 There are probably some other bugs too, since this has not been
