Merging lai's source with this one is very irritating because they have different indentation styles. I couldn't find what profile vegard used for his version, so I used these flags (which should bring the source close to KNF): -bap -br -ce -ci4 -cli0 -d0 -di0 -i8 -ip -l79 -nbc -ncdb -ndj -ei -nfc1 -nlp -npcs -psl -sc -sob
