Hi,

This is an elegant solution if only I could make it work.  The  
COMMAND is not built before it's used in the actions.  It may be that  
the way I'm using it is the problem, not sure.  This is what I've got  
so far.

# xmldb.jam
feature inline-binary : : free dependency ;
toolset.flags xmldb.concat.xml COMMAND <inline-binary> ;

type.register XML : xml ;
type.register XMLDB : xmldb ;
generators.register-composing xmldb.concat.xml : XML : XMLDB ;

actions xmldb.concat.xml bind COMMAND
{
   $(COMMAND) $(<) $(>)
}

# xmlconcat.jam
exe xmlc : $(source-files) ;

# parser.jam
import xmldb ;
xmldb foo.db : main.xml : <inline-binary>/xmlconcat//xmlc ;

When I build, the value of COMMAND is bin/xmlconcat/gcc-3.4.3/debug/ 
xmlc but there is no executable in that directory, so it doesn't  
appear to be building it before using it.  Can you see what I'm doing  
wrong?

Thanks.
