// SymSpell: 1000x faster through Symmetric Delete spelling correction algorithm
//
// The Symmetric Delete spelling correction algorithm reduces the complexity of edit candidate generation and dictionary lookup
// for a given Damerau-Levenshtein distance. It is three orders of magnitude faster and language independent.
// Opposite to other algorithms only deletes are required, no transposes + replaces + inserts.
// Transposes + replaces + inserts of the input term are transformed into deletes of the dictionary term.
// Replaces and inserts are expensive and language dependent: e.g. Chinese has 70,000 Unicode Han characters!

This bash snippet is a script to migrate svn repository with a structure (trunk, branches and tags) to a new git repository. It take care of doing authors matching and remove the adress of old svn
View svn2git.bash

You can’t perform that action at this time.
