Cleaning up bash releases at first directory level

[uzibalqa]

I would much value that tho bash manual includes a chapter about installing  
new version.  For instance I need to use some new feature from "Bash 5.2" but 
looking at the bash tree, there are a lot of files.

In Emacs for instance, one would find a limited number of files at the first 
directory level.  It is easy to understand because one will find only the 
important parts for users.  Basically readme, install, autogen, configure, 
changelogs, copying, 

Not so for Bash 5.2.  Where at the first directory level one is barraged with a 
multitude of source files, rather than sticking with the ones needed for 
installation only.  I would appreciate if things would be cleaned up.
