Hello, I have the following questions to consult and look forward to your
authoritative answers.
1. Must various software packages in the Debian community contain a license
file "license.txt"? Without this file, how does the users know about the
license usage of the package?
2. I found that each software package has a "Copyleft" document, and a lot of
license information is also listed in this document. Therefore, I would like to
ask, when the two documents "license.txt" and "Copyleft" exist in the software
package at the same time, which one should the user take as the basis, and how
to deal with the situation where the declared license information of the two
documents is inconsistent, Which shall prevail?
3. If the software package only contains "Copyleft" documents, can users refer
to the license information declared in this document?
