 Note that this was developed with udev version 024.
 
 - Make sure you've installed udev and that it is working properly.

-  This will compile udev with gcov support.  Basically make_gcov.sh will
-  run make but override the CFLAGS.  It strips any optimization from
-  CFLAGS in order for gcov to get correct code coverage analysis.  It will
-  also add the -fprofile-arcs and -ftest-coverage options which are the
-  necessary flags needed to use gcov.

-  If you look into your udev directory and see that it has been polluted with

 - Then execute some udev tasks.  You can run some udev tests, reboot, or
   do anything your little udev heart desires.  Once you are satisfied, you
   can now see how much udev code was covered.  I personally recommend just
   running test/udev-test.pl for starters.
