In a recent post a particular package was mentioned. I was not familiar with it. I went to appropriate URL under https://manpages.debian.org/buster .
It did not explicitly answer my question.However, under "SEE ALSO" it stated that additional documentation would be under /usr/share/doc/... .
*PROBLEM* As package is not installed, that directory does *NOT* exist. Where to find referenced documentation on the web? NOTE BENE This post is about man pages as a class.
