Poedit

POO files are files that are used to translate software applications into various languages. They are compiled as catalogs in the Gettext library, and you can edit them as text, or even using an editor like Poedit.

Poedit lets you easily work with PPO files, since you just want to translate, word for word, all words and expressions used in the original language of the file.

You can save a database translation to use them later, and you can also bookmark the program that can currently be used to edit the existing catalog, or to create new ones.

Finally, this app is compatible with C, C, Java, Perl, PHP, Python, TCL and Delphi, this allows you to update the catalog from the HTML file, and it gives you the option of compiling it in a .mo file, finally, use in applications will do.
