I'll try to explain how I have developed the French, German and Spanish dictionaries for the NetBeans online spellchecker : we will (re)build a French dictionary for NetBeans 7.3.
- expand GNU Aspell dictionaries files.
- checkout the NetBeans 7.3.0 FCS sources from Mercurial repository.
- open the English dictionary project and make a copy.
- modify the copied project.
- make the NBM file and test it.
- (optional) sign the NBM file and submit it to the community for validation.
