psl

Bindings to libpsl, a C library that handles the Public Suffix List (PSL).

The PSL is a list of domains where there may be sub-domains outside of the administrator's control.
e.g. the administrator of '.com' does not manage 'github.com'.

This list has found use in many internet technologies including:
- preventing cross-domain cookie leakage
- allowance of issuing wildcard TLS certificates
