How to use multilarge_nlinear?

I'm trying to figure out how to use this library in order to do nonlinear least-squares fitting using multilarge_nlinear but this library doesn't seem to have the high level driver that the original GNU library does. I am, however, finding a gsl_multilarge_nlinear_solver in this library which doesn't seem to match up (type vs. function, etc).

I've scoured both this documentation and the GNU documentation but it's been a really long time since I've done anything in C and I'm having a hard time figuring this out. Can someone provide an example of how to use this library for nonlinear least-squares fiting for large systems (multilarge_nlinear)?
