Comment:
I'll see if I can figure out the build.rs format so I can submit a patch with build instructions for the man files. As for the PAM stuff, the configuration file here was lifted from [the Arch package](https://aur.archlinux.org/cgit/aur.git/tree/greetd.pam?h=greetd), which is maintained by greetd's author. I know that doesn't automatically make it trustworthy, but I think it proves a solid base.
