[NTG-context] typescript

I am trying to get a minimal working example so that I have something to tinker with. C:\contextminimal\tex\texmf-local\type-garamondprem.tex contains only: \starttypescript [serif] [garamondprem] \definetypeface [garamondprem] [rm] [serif] [name:garamondpremrpromed] [default] \stoptypescript (garamondpremrpromed is a name returned by mtxrun --script fonts --list --all --pattern=*Garamond*.) I run: luatools --generate and texmf-local is found. In my preamble: \usetypescriptfile [type-garamondprem] \usetypescript [garamondprem] \setupbodyfont [garamondprem,12pt] When I run Context, the result contains only Latin Modern.
