\section{Cleaning up and packaging}
\label{section:cleanup}
\par
Let's say we've just created the {\tt spooles.a} library and then
typed {\tt make all\_drivers} when in the {\tt spooles} directory.
All the executable programs are now on disk,
and taking up a lot of space.
To remove all the executable programs, we don't need to go into
each object's {\tt driver} program and remove them one by one.
We can do this from the top level directory by typing
{\tt make clean}.
\par
This process visits each of the objects' {\tt src/}, {\tt doc/} and
{\tt drivers/} directories one by one.
In the {\tt src/} directories, any {\tt *.o} and {\tt *.a} files
are removed.
In the {\tt doc/} directories, any {\tt *.dvi} files are removed.
In the {\tt drivers/} directories, any {\tt *.o} and {\tt *.a} files
are removed, as well as all driver program executables.
(The {\tt makefile} in a drivers directory keeps track of the
driver programs in the {\tt DRIVERS} variable.
Modify this as necessary if you add a driver program to the
directory.)
\par
Let's say you've got {\bf SPOOLES} working on one system and you
want to move it to another system.
Even after cleanup (via the {\tt make clean} call) there may be a
large number of files that don't need to be moved.
Or perhaps you'd like to {\tt tar} everything that is necessary without
removing your {\tt spooles.a} library and executables that took so
long to compile.
\par
The {\tt dotar} shell script is used to package up everything that
is necessary into one tar file.
You should modify this as necessary.
Here are the lines from {\tt dotar} that archive what is necessary
from the {\tt A2} object.
\begin{verbatim}
A2.h \
A2/{*.h,makefile} \
A2/src/{makefile,makeGlobalLib,*.c} \
A2/drivers/{do*,makefile,*.c} \
A2/doc \
\end{verbatim}
This {\tt tar}'s the header file and middle level makefile,
then goes into the {\tt src/} directory and {\tt tar}'s the makefiles
and source code,
then goes into the {\tt drivers/} directory
and {\tt tar}'s the makefiles, driver programs and shell scripts,
and then {\tt tar}'s everything in the {\tt doc/} directory.
This happens for every object, with a few minor exceptions.
