Most of the changes consist in small updates to Makefile and make.depend and
in the replacement of module "parameters" with "upf_params" whenever variables
lmaxx and lqmax are USEd. Routine "read_pseudo" moved back to Modules/;
"simpsn" moved to upflib/; a copy of "matches" temporarily added to upflib/
Note that everything compiles (except EPW) but nothing has been tested yet!
