I get the following message:

prompt$  
../tools/regression/build/bin/process_jam_log/cray/release/ 
process_jam_log
Usage: bjam [bjam-args] | process_jam_log [locate-root]
   locate-root is the same as the bjam ALL_LOCATE_TARGET
   parameter, if any. Default is boost-root.
boost_root: /u/ph/troyer/boost
locate_root: /u/ph/troyer/boost

I thus added $boost_root to the command. Was that unnecessary, since as  
the output shows it seems to find boost_root? In that case I am  
confused why it prints a usage message.
