ProofLite is a tool for non-interactive proof checking in PVS. Prooflite also enables a semi-literate proving style in PVS where specification and proof scripts reside in the same file (as it is done in Coq and other proof assistants).

ProofLite has been part of PVS since PVS 5.0. The current version of ProofLite is 6.0 and is included in PVS 6.0. ProofLite 6.0 provides:

- A proof script language for writing proofs in
`*.pvs`

files, e.g.,`prooflite_examples.pvs`

. - Emacs commands for installing proof scripts in proofs and for extracting proof scripts from proofs.
- The command line utility
`proveit`

to re-prove theories in batch mode. - The command line utility
`provethem`

to re-prove libraries (collection of theories) in batch mode.
