   Generate code and copy it to DESTDIR (ROOT.jl top directory).

   --force: force deletion of DESTDIR/src, DESTDIR/deps, and DESTDIR/Project.toml
   --update: enable update mode
   --rootfromenv: generate the code from the ROOT installation of the shell environment
                  instead of from ROOT_jll
   --verbosity N: set wrapit verbosity level
   --notest       disable run of ROOT module tests
