| 25 | =head1 NAME␊ |
| 26 | ␊ |
| 27 | Locale::Po4a::Wml - convert WML (web markup language) documents from/to PO files␊ |
| 28 | ␊ |
| 29 | =head1 DESCRIPTION␊ |
| 30 | ␊ |
| 31 | The po4a (PO for anything) project goal is to ease translations (and more␊ |
| 32 | interestingly, the maintenance of translations) using gettext tools on␊ |
| 33 | areas where they were not expected like documentation.␊ |
| 34 | ␊ |
| 35 | Locale::Po4a::Wml is a module to help the translation of WML documents into␊ |
| 36 | other [human] languages. Do not mixup the WML we are speaking about here␊ |
| 37 | (web markup language) and the WAP crap used on cell phones.␊ |
| 38 | ␊ |
| 39 | Please note that this module relies upon the Locale::Po4a::Xhtml␊ |
| 40 | module, which also relies upon the Locale::Po4a::Xml module. This␊ |
| 41 | means that all tags for web page expressions are assumed to be written␊ |
| 42 | in the XHTML syntax.␊ |
| 43 | ␊ |
| 44 | =head1 OPTIONS ACCEPTED BY THIS MODULE␊ |
| 45 | ␊ |
| 46 | NONE.␊ |
| 47 | ␊ |
| 48 | =head1 STATUS OF THIS MODULE␊ |
| 49 | ␊ |
| 50 | This module works for some simple documents, but is still young.␊ |
| 51 | Currently, the biggest issue of the module is probably that it cannot␊ |
| 52 | handle documents that contain non-XML inline tags such as <email␊ |
| 53 | "foo@example.org">, which are often defined in the WML. Improvements␊ |
| 54 | will be added in the future releases.␊ |
