Why should I use otfinstall instead of texfont, besides the fact that texfont doesn't work?

Do you really need another reason? Have you tried otfinst? The point of all these scripts is to make your life easier in generating metrics, auxiliary fonts and map files; if you tear yourself with questions before trying them much of their interest is lost on you.

It is nice to have such scripts. But I would like to know what goes on behind the scene. In principle one has to know all the steps to do it by hand. Wolfgang
