This is a simple module to select the best available implementation of the.standard `diff' algorithm, which works by effectively trying to solve the Longest Common Subsequence (LCS) problem. This algorithm is described in: *A Fast Algorithm for Computing Longest Common Subsequences*, CACM, vol.20, no.5, pp.350-353, May 1977. However, it is algorithmically rather complicated to solve the LCS problem; for arbitrary sequences, it is an NP-hard problem. Simply comparing two strings together of lengths *n* and *m* is O(n x m). Consequently, this means the algorithm necessarily has some tight loops, which, for a dynamic language like Perl, can be slow. In order to speed up processing, a fast (C/XS-based) implementation of the algorithm's core loop was implemented. It can confer a noticable performance advantage (benchmarks show a 54x speedup for the `compact_diff' routine).
