+                    changes file with full pathname (or relative to the
+                    remote home directory) must be given as the main
+                    argument in the rest of the command line.
+    -k<keyid>       The key to use for signing
+    -p<sign-command>  The command to use for signing
+    -e<maintainer>  Sign using key of <maintainer> (takes precedence over -m)
+    -m<maintainer>  The same as -e
+    -S              Use changes file made for source-only upload
+    -a<arch>        Use changes file made for Debian target architecture <arch>
+    -t<target>      Use changes file made for GNU target architecture <target>
+    --multi         Use most recent multiarch .changes file found
+    --re-sign       Re-sign if the file is already signed.
+    --no-re-sign    Don't re-sign if the file is already signed.
+    --debs-dir <directory>
+                    The location of the files to be signed when called from
+                    within a source tree (default "..")
+    --no-conf, --noconf
+                    Don't read devscripts config files;
+                    must be the first option given
+    --help          Show this message
+    --version       Show version and copyright information
+  If an explicit filename is specified, it along with any child .buildinfo and
+  .dsc files are signed. Otherwise, debian/changelog is parsed to find the
+  changes file.
