Note that you'll likely need a recent version of
ftp://ftp.gnu.org/pub/gnu/gengetopt/ (gnu gengetopt) to compile dss.
+Optionally, type
+
+ make man
+
+to create the man page of dss. This invokes help2man so make sure
+that help2man is installed on your system. Note that the man page is
+just the nroff variant of the output of "dss --detailed-help".

dss is known to compile on Linux, MacOS, Solaris, FreeBSD and
NetBSD. However, it is run-tested only on Linux.
