[Boost-build] v2 Exe targets from nested Jamfiles

Hi,

In my Jamroot, I need a list of all the exe targets defined anywhere  
in the nested Jamfiles.  I want to do this so I can have a top-level  
list of all executable targets to install without asking the user to  
enumerate each target explicitly.  Our directory structure is  
arbitrarily named by the user, but the Jamfiles are never more than  
two levels deep.  It's easy to get a list of all the nested Jamfiles

local cwd = [ PWD ] ;
all-jamfiles = [ glob */Jamfile */*/Jamfile ] ;

But I can't see how to grep each Jamfile to get a list of the  
executable targets without writing a custom scanner.  I tried this

all-executables = [ MATCH "^exe (.*)" : $(all-jamfiles) ] ;

which only greps the Jam file name, not the Jamfile contents.  Any  
ideas how to accomplish this?
