  22 %description
  23 RE2 is a C++ library providing a fast, safe, thread-friendly
  24 alternative to backtracking regular expression engines like those used
  25 in PCRE, Perl, and Python.
  26
  27 Backtracking engines are typically full of features and convenient
  28 syntactic sugar but can be forced into taking exponential amounts of
  29 time on even small inputs.
  30
  31 In contrast, RE2 uses automata theory to guarantee that regular
  32 expression searches run in time linear in the size of the input, at
  33 the expense of some missing features (e.g back references and
  34 generalized assertions).
