cruft-ng 0.9.56 (amd64 binary) in ubuntu mantic

 cruft-ng is a program to look over your system for anything that shouldn't
 be there, but is - the so called "cruft"; or for anything
 that should be there, but isn't.
 .
 cpigs is a program that by default works like dpigs
 but for volatile data. It prints out the package with the most volatile
 data (usually apt, plocate...)
 It can also dump it's whole state into a .csv format usable for
 more in depth analysis.
 .
 Both cruft-ng and cpigs base most of their results on
 dpkg's & plocate's databases, and also use a built-in custom
 homegrown ruleset to match volatile files
 to the corresponding engine.
 .
 Packages wanting to document such volatile files can do so
 using dh-cruft.
