we weren't actually using these sources anymore, okay?

-// This library provides APIs to debug the probing behavior of hash tables.
-//
-// In general, the probing behavior is a black box for users and only the
-// side effects can be measured in the form of performance differences.
-// These APIs give a glimpse on the actual behavior of the probing algorithms in
-// these hashtables given a specified hash function and a set of elements.
-//
-// The probe count distribution can be used to assess the quality of the hash
-// function for that particular hash table. Note that a hash function that
-// performs well in one hash table implementation does not necessarily performs
-// well in a different one.
-//
-// This library supports std::unordered_{set,map}, dense_hash_{set,map} and
-// absl::{flat,node,string}_hash_{set,map}.
