Hello, I am coming to ConTeXt from LaTeX and have a typescript question. I
was searching for information on the mailing list about defining semibold
and other font variants, and found the following. Can you tell me if
further information is only available in the book "context mkiv -- Fonts"
or can I find it somewhere else? I have searched through the revised Fonts
chapter of the ConTeXt manual but the \definefontalternative macro and the
approach described here are not documented there.

The approach below works for me if I adapt it to Adobe Garamond Premier
Pro, but I am attempting to build a typescript for that handles optical
weights, small caps, etc and I have not been able to make it work yet.

Before I try posting a minimal example, I would like to be sure that I am
looking at the right documentation. I have looked at the "Fonts in LuaTeX"
page on Contextgarden as well, but I don't think I have a full
understanding of typescripts using OSFONTDIR fonts yet. If there is
something I am missing please let me know.

Thanks,
PPN

Based on ideas from the forthcoming book "context mkiv -- Fonts":

% the semi bold alternatives
