Prepare the sauce while the pasta is cooking to ensure that the linguine will be hot and ready when the sauce is finished.
Bring a large pot of salted water to a boil, add the pasta and cook for 8 to 10 minutes or until tender yet firm (as they say in Italian "al dente.") Drain the pasta well.
Meanwhile, heat the olive oil over medium flame in a deep saute pan with a lid. Add the garlic and red pepper flakes; saute for 2 minutes. Add the clams, wine, and lemon juice. Cover and cook, shaking the pan periodically, until all the clams are opened, about 7 minutes. Discard any that have not opened.
Crank the flame up to medium-high heat. Add the hot, drained linguine to the pan; add the butter and season with salt and pepper. Toss the pasta with the clams to it's nicely coated. Shower with chopped parsley and toasted bread crumbs. Drizzle with a nice dose of olive oil before serving.
