Subject: [PATCH] Use proto_dist from command line
369b33
369b33
Use protocol distribution value from command line when provided instead
369b33
of always using default value (inet_tcp) when trying to check epmd.
369b33
369b33
If provided more than one protocol distribution types, then use the
369b33
first one.
