When i generate a font using makeotf directly or robofont, it adds in a Version string (see the attached screenshot) the versions of each library that built the font (in this case, makeotflib, hotconv, et al).
What i would like to do is specify a version string on generation (or even after the fact, whatever), but i don't actually know how to modify this field for a generated font. I suspect this is a trivial operation, but it is eluding me.
primarily, i would like to be able to tag a release with a short hg or git commit hash so i can see how old an installed version is when i switch to a new computer or ask a friend if they have the latest version. right now, i have to look at the file creation date and sorta just guess, but i'd rather command-i the file and be able to see how aged the file is.
thanks for any help.
