directory and a few files called Action in some directories.
The Action files describe in a very simple form which actions
have to be performed in which directories.
-The default action is to start "make install".
+The default action is to start "make install && make clean".
The output of each make is diverted to a file called "Out"
in the same directory as the make was started in.
If the make was successful (return code 0) the Out file is removed
