-s SMARTCTL Use SMARTCTL for syntax check ('-s -' to disable)
[default: $SMARTCTL]
-t TOOL Use TOOL for download: $os_dltools
[default: first one found in PATH]
-u LOCATION Use URL of LOCATION for download:
sf (Sourceforge code browser via HTTPS)
svn (SVN repository via HTTPS) [default]
svni (SVN repository via HTTP)
trac (Trac code browser via HTTPS)
--cacert FILE Use CA certificates from FILE to verify the peer
--capath DIR Use CA certificate files from DIR to verify the peer
--insecure Don't abort download if certificate verification fails
--dryrun Print download commands only
-v Verbose output
Updates $DRIVEDB
or DESTFILE from smartmontools SVN repository.
