Dear Maintainer, There used to be a HTML manual describing the arguments of 7z command in more detail than the summary included in the man page. In particular, it described how to set the chain of compression methods and their parameters with the -m option. The manual used to be packaged in p7zip-full, and upstream still seems to distribute it in their binary packages, but the information contained in it is nowhere to be seen in any form in the current 7zip package.
Hello Kacper, I send ITP request for 7zip documentation package. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1146125 You can examine current status of the package from here. https://salsa.debian.org/yokota/7zip-doc
Looks good. Thanks for such a quick reply!
