hi Jeremy, all,
gnome-snapshot does not accept any arguments nor does it have any configuration files. Therefore, there is nothing to document with a manpage.
On the contrary, apart from the usual minimal information required in Debian, a description of the buttons' meanings and the expected behaviour would be useful so that the user doesn't have to guess.
I am closing this bug since we will not provide a manpage that isn't useful.
You don't have to provide an upstream man page if you don't wish to, but the Debian policy is clear: https://www.debian.org/doc/debian-policy/ch-docs.html#manual-pages "Do not close the bug report until a proper man page is available." "Even though the GNU Project do not in general consider the lack of a man page to be a bug, we do; if they tell you that they don’t consider it a bug you should leave the bug in our bug tracking system open anyway." Cheers Boud
