   // This contains the main function for the aggregate command line that allows to specify
   // one of the Marian executables as the first argument. This is done by including all
   // individual .cpp files into a single .cpp, using a #define to rename the respective
   // main functions.
   // For example, the following two are equivalent:
   //  marian-scorer ARGS
   //  marian score  ARGS
   // The supported sub-commands are:
   //  train
   //  decode
   //  score
   //  embed
   //  vocab
   //  convert
   // Currently, marian_server is not supported, since it is a special use case with lots of extra dependencies.
