fnbool initConfigOptions(CFG)(ref CFG cfg, string cfgname)initialize members of struct CFG from rt_config options

fnbool parseOptions(CFG)(ref CFG cfg, string opt)initialize members of struct CFG from a string of sub-options.

fnbool rt_parseOption(T)(const(char)[] optname, ref inout(char)[] str, ref T res, const(char)[] errName)Parses an individual option `optname` value from a provided string `str`. The option type is given by the type `T` of the field `res` to which the parsed value will be written too. In case of an er...
