Modul:Citation/CS1/Configuration

Denne modulen og dens undermoduler er «motoren» bak CS1-stilen og de ulike kildemalene som følger denne ({{Kilde bok}}, {{Kilde www}}, osv…). Modulen er importert fra en:Module:Citation/CS1 og tilpasset norske forhold. De viktigste tilpasningene er i Modul:Citation/CS1/Configuration og Modul:Citation/CS1/Date validation, men det er gjort tilpasninger i omtrent alle undermodulene, så ved behov for å re-importere må man passe på dette. Re-importer alltid til sandkassene først.

Skal du gjøre endringer i denne modulen eller en av modulens undermoduler, prøv alltid i den tilhørende sandkassen først. Det finnes sandkasseversjoner av alle kildemalene som benytter Modul:Citation/CS1/sandkasse: {{Kilde bok/sandkasse}}, {{Kilde www/sandkasse}}, osv…, slik at du kan se hvordan disse blir påvirket av endringene dine.
