NAME
simstring - build database and find similar words

SYNOPSIS
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.

-s, --similarity=SIM
    pecify a similarity measure (DEFAULT='cosine'):

-t, --threshold=TH
    specify the threshold (DEFAULT=0.7)

-e, --echo-back
    echo back query strings to the output

-q, --quiet
    suppress supplemental information from the output
