OCRopus is being developed primarily for book recognition right now. Its components are useful for building a license plate reader, but license plate recognition requires special image pre-processing and normalization. So, you still need to add some code and then tie it all together with scripting. The new character recognition code in 0.4 should help a lot.
The way to get started with this is to read some papers on the problem and decide on an approach. Then you can take inventory of what parts are already implemented in OCRopus and what you still may need to add. The other thing you need for a license plate reader is training and test data: images/video of actual license places, together with ground truth, preferably at the character level.
