| − | That's what this part of the project should achieve:
| + | |
| − | * reading and parsing of MO files containing the strings and their translations
| + | |
| − | * organize the object collection in an incremental way: don't load the whole file if it's not needed
| + | |
| − | * give a simple interface to the localization class, so that the strings can be printed out without too much efforts
