+:Obsession {file}       Invoke |:mksession| on {file} and continue to keep it
+                        updated until Vim exits, triggering on the |BufEnter|
+                        and |VimLeavePre| autocommands.  If the file exists,
+                        it will be overwritten if and only if it looks like a
+                        session file.
+
+:Obsession {dir}        Invoke |:Obsession| on {dir}/Session.vim.  Use "." to
+                        write to a session file in the current directory.
+
+:Obsession              If session tracking is already in progress, pause it.
+                        Otherwise, resume tracking or create a new session in
+                        the current directory.
+
+:Obsession!             Stop obsession and delete the underlying session file.
+
+Loading a session created with |:Obsession| automatically resumes updates to
+that file.
