===Modules===
Of course, functions can be compiled into groups and then placed into Python modules for widespread re-use throughout your SConstructs.  Commonly used Python modules are currently located in <tt>&#36;RSFROOT/book/Recipes</tt>, which is where you should place your modules as well.  As usual, you must use correct Python syntax to access functions contained within modules.  For example, if you create a module called myutil.py, then you can access your functions in the following manner:
<syntaxhighlight lang="python">
import myutil
myutil.ricker(...)
</syntaxhighlight>
