[SciPy-Dev] Algorithm for butterworth filter implementation

Could someone provide me with some hints about the algorithm used to compute 
the coefficients for the butterworth filter found in scipy ? I am interested 
in the passband version of this filter since concatenating a low pass and a 
high pass filter does not produce the same frequency response as the passband 
filter provided by scipy.
