thimk

thimk (an old joke) is a command-line spelling word suggestion tool. You give it a possibly-misspelled word, and it spits out one or more properly-spelled words in order of likelihood of similarity. The latest change to the implementation is an addition of an optional precompiled SQlite database of phonetic codes for the entire dictionary, created with thimk-makedb. This greatly speeds lookup, permitting reasonable performance on enormous dictionaries.
