[Scons-users] tutorial

[Jitterman]

All,
    I am trying to learn to use Scons for the first time, but I am not using it 
for C or for Java. I am finding the existing documentation a bit frustrating 
because it all seems to assume that you are using some language such as C for 
which Scons already has built in support. Thus, the examples are very terse 
(just put "Program('hello.c')" in your Sconstruct file and run scons, and viola, 
you are done). This of course assumes that Scons already has all the rules it 
needs to build the program.

What I need to a tutorial for how to build a program where it is not assumed 
that Scons already has all the rules it needs because I would like to understand 
how to add those rules.

My particular situation is that I would like to use Scons to create and compile 
a cython version of an existing python program, where some of the python files 
are generated programatically. So I need to know how to write rules like:
    generatedFile1.py: sourceFile1.py
        python sourceFile1.py
    %.pyx: %.py
        ln -s $% $@
    %.c: %.pyx
	cython $%
    ...

Can anybody point me to a tutorial like that?
