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