393 ./tmpl_process3.pl [ I<tmpl_process.pl options> ]
397 This is an alternative version of the tmpl_process.pl script,
398 using standard gettext-style PO files. While there still might
399 be changes made to the way it extracts strings, at this moment
400 it should be stable enough for general use; it is already being
401 used for the Chinese and Polish translations.
403 Currently, the create, update, and install actions have all been
404 reimplemented and seem to work.
412 Translation files in standard Uniforum PO format.
413 All standard tools including all gettext tools,
414 plus PO file editors like kbabel(1) etc.
419 Minor changes in whitespace in source templates
420 do not generally require strings to be re-translated.
424 Able to handle <TMPL_VAR> variables in the templates;
425 <TMPL_VAR> variables are usually extracted in proper context,
426 represented by a short %s placeholder.
430 Able to handle text input and radio button INPUT elements
431 in the templates; these INPUT elements are also usually
432 extracted in proper context,
433 represented by a short %S or %p placeholder.
437 Automatic comments in the generated PO files to provide
438 even more context (line numbers, and the names and types
443 The %I<n>$s (or %I<n>$p, etc.) notation can be used
444 for change the ordering of the variables,
445 if such a reordering is required for correct translation.
449 If a particular <TMPL_VAR> should not appear in the
450 translation, it can be suppressed with the %0.0s notation.
454 Using the PO format also means translators can add their
455 own comments in the translation files, if necessary.
459 Create, update, and install actions are all based on the
460 same scanner module. This ensures that update and install
461 have the same idea of what is a translatable string;
462 attribute names in tags, for example, will not be
463 accidentally translated.
469 Anchors are represented by an <AI<n>> notation.
470 The meaning of this non-standard notation might not be obvious.
472 The create action calls xgettext.pl to do the actual work;
473 the update action calls xgettext.pl and msgmerge(1) to do the
478 xgettext.pl must be present in the current directory; the
479 msgmerge(1) command must also be present in the search path.
480 The script currently does not check carefully whether these
481 dependent commands are present.
483 Locale::PO(3) has a lot of bugs. It can neither parse nor
484 generate GNU PO files properly; a couple of workarounds have
485 been written in TmplTokenizer and more is likely to be needed
486 (e.g., to get rid of the "Strange line" warning for #~).
488 This script may not work in Windows.
490 There are probably some other bugs too, since this has not been
