WWW.EASA.EU.ORG holds the basic regulation IR PART-66 that will give you lots of information regarding the licence set up in Europe, this includes the examination syllabus and prerequisites to obtain the basic licence and type endorsements.
English or German NAA (National Aviation Authority) are the licences taken in highest regard to other authorities if you say want to go and work elsewhere, personally, take your exams with either of them.
If you do wish to work on French Registered Aircraft a French Legislation exam will be required to endorse the European licence that will be recognised by them anyway under EASA.
My NAA the CAA do an excellent Engineers Licence Guidance Document on their website
www.caa.co.uk and search ELGD.
Good Luck
