Ott [08-Jan-2007, version 0.10.2, Alpha] Has a documentationHas a tutorial
tool for semantic definitions of programming languages and calculi. The tool takes as input a definition of a language syntax and semantic relations, in a concise and readable ASCII notation that is close to what one would write in informal mathematics. It builds parsers for symbolic and concrete terms of the language, generates LaTeX to build a typeset version of the definition, and generates Coq, HOL, and Isabelle versions of the definition.

Bedwyr [06-Nov-2006, version 1.0, Stable] Has a documentation
Bedwyr is an extended logic programming language that allows model-checking directly on syntactic expressions possibly containing bindings. We believe that it's an interesting tool for computer scientists, as it allows simple reasoning on declarative specifications, with several good examples, notably bisimulation checking for the pi-calculus. Other examples include type systems, games, logics, etc.

HOL-light [22-May-2006, version 2.20, Stable] Has a documentationHas a tutorial
HOL Light is a computer program to help users prove interesting mathematical theorems completely formally in higher order logic. It sets a very exacting standard of correctness, but provides a number of automated tools and pre-proved mathematical theorems (e.g. about arithmetic, basic set theory and real analysis) to save the user work. It is also fully programmable, so users can extend it with new theorems and inference rules without compromising its soundness.

NML [08-Jul-2004, Beta]
a dynamically typed functional language whose syntax conforms closely to that of OCaml. In addition, it supports overloaded, vectorized, math operations, list comprehensions, and optional and keyword arguments in uncurried argument tuples, possibly with specified default values. It can access OLE compliant, and low-level COM interfaces, supports serial I/O and socket based communication, and provides an ADO connection to external databases. An Emacs mode is supported through a hacked Tuareg interface, as well as a Tcl/Tk interactive browser and interaction window with list pane access to a user modifiable documentation database.

Phox [24-Apr-2002, version 0.83, Beta] Has a documentation
PhoX is a proof assistant based on High Order logic and it is eXtensible. One of the principle of this proof assistant is to be as user friendly as possible and so to need a minimal learning time. The current version is still expirimental but starts to be really usable. It is a good idea to try it and make comments to improve the final version.

Focalize [14-Jan-2013, version 0.8.0, Beta] Has a documentation
FoCaLize is an integrated development environment to write high integrity programs and systems. It provides a purely functional language to formally express specifications, describe the design and code the algorithms. Within the functional language, FoCaLize provides a logical framework to express the properties of the code. A simple declarative language provides the natural expression of proofs of those properties from within the program source code.

Hansei [02-Jun-2009, Development code] Has a documentation
HANSEI is the the embedded domain-specific language for probabilistic programming: for writing potentially infinite discrete-distribution models and performing exact inference, importance sampling and inference of inference. HANSEI is an ordinary OCaml library, with probability distributions represented as ordinary OCaml programs. Delimited continuations let us reify non-deterministic programs as lazy search trees, which we may then traverse, explore, or sample. Thus an inference procedure and a model invoke each other as co-routines. Thanks to the delimited control, deterministic expressions look exactly like ordinary OCaml expressions, and are evaluated as such, without any overhead. Inference procedures and probabilistic models are both ordinary OCaml functions. Both may be defined and extended by library users; both may appear in each other's code. Performing inference on a model that includes calls to inference procedures lets us parameterize distributions by distributions, and lets inference procedures measure their own accuracy. One application is modeling agents reasoning about each other's limited reasoning.
