This is the user manual of Ssreflect, a set of extensions to the proof scripting language of the Coq proof assistant. While these extensions were developed to support a particular proof methodology - small-scale reflection - most of them actually are of a quite general nature, improving the functionality of Coq in basic areas such as script layout and structuring, proof context management, and rewriting. Consequently, and in spite of the title of this document, most of the extensions described here should be of interest for all Coq users, whether they embrace small-scale reflection or not.
