3.3. Making a list of files with Glob()

You can also use the Glob() function to find all files matching a certain template, using standard the shell pattern matching characters *, ?, and [abc] to match any of a, b, or c. [!abc] is also supported, to match any character except a, b, or c. This makes many multi-source-file builds quite easy:

       Program('program', Glob('*.c'))
    

The SCons man page has more details on using Glob() with Variant dirs and Repositories and returning strings rather than Nodes.
