By default, scons outputs files at the top level of the SConscript file it is operating on. Thus, if I have frontends/SConscript, it will output stuff by default at frontends/. I'm not sure if this is desired. Do you prefer everything in it's own subdirectory (ie, the csound binary in frontends/csound/csound), or everything at the top level (which is how SConstruct behaves now)? -- Felipe Sateler
