Package: clang-5.0 Version: 1:5.0-4 The sancov-5.0(1) manpage reads:
The full documentation for sancov is maintained as a Texinfo manual.
If the info and sancov programs are properly installed at your site,
the command
info sancov
should give you access to the complete manual.
But there's no such info page. -- Jakub Wilk
