Can't see what Ramanujan did there

If the infinite continued fraction 11+e2π1+e4π1+ \cfrac{1}{1+\cfrac{e^{-2\pi}}{1+\cfrac{e^{-4\pi}}{1+\cdots}}} can be expressed as eaπb(b+bac+ba)e^{\dfrac{a\pi}{b}}\left(\sqrt{\dfrac{b+\sqrt{b}}{a}}-\dfrac{c+\sqrt{b}}{a}\right) where a,ba,b and cc are coprime integers,find a+b+ca+b+c.
