/*
 This is the routine that can be called to initialize the R environment
 when it is embedded within another application (by loading libR.so).

 The arguments are the command line arguments that would be passed to
 the regular standalone R, including the first value identifying the
 name of the `application' being run.  This can be used to indicate in
 which application R is embedded and used by R code (e.g. in the
 Rprofile) to determine how to initialize itself. These are accessible
 via the R function commandArgs().

 The return value indicates whether the initialization was successful
 (Currently there is a possibility to do a long jump within the
 initialization code so that will we never return here.)

 Example:
     0) name of executable
     1) don't load the X11 module
     2) don't show the banner at startup.
