[Scons-users] How do you get scons to clean up side-effect files?

[M Busche]

I tried to send this once before, but I don't think it showed up.

I'm using scons with gcc on ubuntu.  I'm both an scons and python noob,
but I've managed to get Scons to build my unit-test application with the
compiler options necessary for gcov/lcov code coverage analysis.  Here
is a much stripped and simplified version of my SConscript file sufficient
to show my problem:

obj = Object(
    "mytest.cpp",
    CPPPATH=Split("/home/matt/dev/gtest/gtest-1.6.0/include"),
    CCFLAGS=Split("-Wall -fprofile-arcs -ftest-coverage"))

Program(
    obj,
    LIBS=Split("gtest pthread gcov"),
    LIBPATH=Split("/home/matt/dev/gtest/gtest-1.6.0/"))

Running scons will create mytest.o and mytest (executable), but (due to
the -fprofile-arcs and -ftest-coverage compiler options) also creates the 
file mytest.gcno needed for subsequent code coverage analysis.  This is 
exactly what I wanted.  But I'd like scons -c to remove this gcno file. 
It does not.  How can I modify the simple SConsctruct file above to 
clean this file at the same time mytest.o is cleaned?  I've seen a few
postings about emitters, but the stuff I've read does not make it clear to
me how to use an emitter with the existing Object Builder.

Much thanks.
