Thank you for the reply.

I was aware that I can install fonts in ` tex/texmf-fonts `. However, the
idea behind my odd request was the need to have the entire project
contained in a single directory. which I can share with people and compile
on any computer with a working TeX Live, without them having to install any
fonts or dependencies.

I tried setting the RUNTIMEFONTS env variable, and it does exactly what I
want. The fact that it leaves garbage in the cache that can influence
other, unrelated projects, is a bit unsettling, I guess I'll just have to
remember to tell people to clean the cache.

Thanks again,

Krešimir
