mdl is the implementation of Russell logical framework. This is a language for pure mathematics, build upon a Metamath language as a high level superstructure. mdl will support fully automatic proving facility.

In fact, mdl program is a compiler from a relativily high-level language for the representation of formal mathematics to the simple and robust for checking language Metamath.

The package contains folowing programs:

• mdl : the mdl prover and the compiler from russell language to Metamath.
• mm : the Metamath translator to smm.
• metamath : original Metamath checker.
• smm : the verifier and translator from smm to russell (simplified Metamath)

mdl uses some boost libraries: spirit, string algos, filesystem. To be sure all of these are avaliable, install libboost-all-dev (linux). Also Intel Threading Building Blocks (tbb) library is used, libtbb-dev (Ubuntu).

To make a complete local build and run translation test just execute ./run script. Math libraries, transleted to smm and Russell will be inside math/tmp directory
