Hello,

I would like to auto-generate a jam file and then have it get used in the current running bjam process.  I have tried using the SHELL rule and/or the response rule like this:

test =@(../../../Jamroot.jam:E="project test ;" ) ;     or test = [ SHELL "echo 'project test ;' >../../../Jamroot.jam" ];

and in both cases the file is generated but the current bjam instance does not see it since the following prints nothing until bjam is rerun:

echo  [ glob ../../../*.jam ] ;

this is also the case with other command like use-project, ....

Is there a way to force bjam to rescan the file system for a particular file?

Thanks,

Chris
