%description
TRE is a lightweight, robust, and efficient POSIX compliant regexp
matching library with some exciting features such as approximate
(fuzzy) matching. At the core of TRE is a new algorithm for regular
expression matching with submatch addressing. The algorithm uses
linear worst-case time in the length of the text being searched,
and quadratic worst-case time in the length of the used regular
expression. In other words, the time complexity of the algorithm
is O(M2N), where M is the length of the regular expression and N
is the length of the text. The used space is also quadratic on the
length of the regex, but does not depend on the searched string.
This quadratic behaviour occurs only on pathological cases which are
probably very rare in practice.
