    You probably mean Cauchy-Goursat. Did you [ask google](http://www.google.ch/search?q=cauchy+goursat+examples)? Clicking this link should give you quite a few hits.2011-07-10

    Deformation of contour refers to homotopy. This whole machinery is dealt with nicely in John Conway's complex analysis book.2011-07-10

Contour integrals in the complex plane can't be interpreted in terms of length or area.
