It takes a bit of contemplation and the realization that there are different measurements for some components of French bikes of that era from the components used on British, Japanese and Italian bicycles. The rest of it is very do-able with a couple bicycle-specific tools. A crank fastener, proper freewheel tools, bottom bracket spanners, pedal wrench, chain tool. You can get by with those and a pretty much standard wrenches and allen keys.
