For an internationalized Swing application with .properties files, one per language, I need a tool to manage these .properties files.
To be more specific: When I change a string in the default language properties file, I need a tool for translators to run in order to copy the added/changed/removed strings into their respective language files.
I found the ResourceBundle plugin for Eclipse, but I don't really want to enforce a heavy application like Eclipse on translators. It would seem like a huge overkill. A text based tool would be preferable.
This question asker seems to be seeking for the same tool as I do, but seems to never have found a solution.
I also found gettext-commons which is a lib that enables use of gettext po files in a Java application. If I don't find a suiting solution for managing the .properties files, I might start using this instead.
