The namespace RooFit contains mostly switches that change the behaviour of functions of PDFs
(or other types of arguments).
 
These switches are documented with the relevant functions, e.g. RooAbsPdf::fitTo().
For an introduction to RooFit (not the namespace), check the [user's guides](https://root.cern.ch/root-user-guides-and-manuals),
