what's this package for?

hi, any reference papers for this package?

Hi, thanks for asking, and sorry it's not better documented.
There is a publication that this was developed for here: https://www.sciencedirect.com/science/article/pii/S1369847814000898
and I've attached it here.
I don't have any user documentation written for the package, but if you're interested, I can share some simple scripts showing how I use it to compute TTC.
