How are UTRRS IndicFontFeatureGSUB.txt files generated?

[Dave Crossland]

Hi!

https://fedorahosted.org/utrrs/ says the source is available at
https://git.fedorahosted.org/git/utrrs.git/ but this 404s, the correct
URL is https://git.fedorahosted.org/cgit/utrrs.git

Browsing the source, I see many files like
https://git.fedorahosted.org/cgit/utrrs.git/tree/utrrs/lang/ta_IN/font/da...

How are these files generated?
