libeet1 1.21.1-5 (armhf binary) in ubuntu focal

 Eet is a tiny library designed to write an arbitrary set of chunks of data to a
 file and optionally compress each chunk (very much like a zip file) and allows
 fast random-access reading of the file later on. It does not do zip as zip
 itself has more complexity than needed, and it was much simpler to implement
 this once here.
 .
 It's small, fast, and does a job. It's heavily commented and fully documented.
 .
 This is part of the Enlightenment Foundation Libraries (EFL).
