Locale::Po4a::Prop - convert Java property and OSX/NeXTSTEP strings from/to PO files

Locale::Po4a::Prop is a module to help the translation of Java property and
OSX/NeXTSTEP strings files into other [human] languages.

The module searches for lines of the following format and extracts the quoted

NOTE: If the text is not quoted, it will be ignored.
