Is it possible to put comments in the client config files (those in the path specified by "client-config-dir") for OpenVPN, i.e. something beginning with "#" or "//" or the like? If so, what is the appropriate comment character?

As Jim says the examples on the OpenVPN site use # for comments and ; to comment out settings. There is no functional difference but this convention makes it easier to visually identify settings that are commented out.
