Continuation lines

If your input lines get very long then editing them using vi and other such text editors becomes a massive pain in the arse. We at PLUMED are aware of this fact and thus have provided a way of doing line continuations so as to make your life that much easier - aren't we kind? Well no not really, we have to use this code too. Anyway, you can do continuations by using the "..." syntax as this makes this:

DISTANCES ATOMS1=1,300 ATOMS2=1,400 ATOMS3=1,500

(see DISTANCES)

equivalent to this:

DISTANCES ...
# we can also insert comments here
  ATOMS1=1,300
# multiple kewords per line are allowed
  ATOMS2=1,400 ATOMS3=1,500
#empty lines are also allowed

... DISTANCES
