Depends on what you want.  You can embed running strings with 
newlines using triple-quotes (either single- or double-quotes):

  TITLE = """Efficiency...
    (cphstl:..."""


Or you can use string concatenation using line-continuations:

  TITLE = "Efficiency..." \
    "(cphstl:..."

or using parens

  TITLE = ("Efficiency..."
    "(cphstl:...")



I like the clean'ness of the first version, but sometimes get 
irked by it including my leading whitespace (there are some 
workarounds, but all involve more than trivial effort).  I tend 
to use the 2nd in the case you describe, but usually using the 
3rd version in all other cases where it's as a parameter to a 
function call or some other bracketed/braced construct.
