+Below in the table you can see what options are suported by which reader/writer (it is possible that the data format can support more).
+ASCII is not a real option and will be selected, if binary was not defined.

 The program does not more than providing a command line based
 interface to select the option bits for reading/writing and to request
 mesh properties. Hence illegal combinations are possible and will
 result in a failure of the program. (The input file won't be damaged
 in this case, but be careful where you put the ouput file!)
-Please note that the Options::ColorFloat is currently only implemented for PLY
-and OFF files.
