Hi Steven,
 Thanks.  I should be able to fix it using this info. However I have hit
another, but somewhat related, roadblock.  Tried  the documentation but
failed to find relevant snippets.

Using generators i have created these two custom rules
1) mp a : a.gp ;
            which converts a.gp to a.mp
2) mps a : a.mp
            which converts a.mp to a.mps

Invoking bjam complains "unable to find target a.mp".  The problem is that I
am unable to specify that "a.mp is generated by rule 1".
In case i am missing something obvious please point me to relevant portion
of the documentation.

Thanks
sandeep
