simstring [OPTIONS]

DESCRIPTION

This utility finds strings in the database (DB) such that they have similarity, in the similarity measure (SIM), no smaller than the threshold (TH) with queries read from STDIN. When -b (--build) option is specified, this utility builds a database (DB) for strings read from STDIN.
