Yes.  Thanks for the suggestion, I have implemented this using config-cache.jam as an example on how to create the batch setup files.  I have it working except for the following issues:

-          I would like the setup batch files to be rooted in the build directory for the jamroot regardless of where the command is executed.  The example in build-system.jam (line 689) on how to do this looks 'scary' per the comment and in the msvc.init I would presume these things are not even available yet.  Any suggestion on how to get this directory?

-          I am also writing the batch file creation action to a log file and was hoping that the actions performed (one batch file per cpu) would all be logged to the file specified in the UPDATE_NOW rule but apparently this rule overwrites rather than appending.  The only way around this that I can think of is to generate all the cpu specific batch files in one action (if I can figure out how to do this) and have a log file per compiler version. Is this the only option?

Thanks,

Chris
