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:
proveitto re-prove theories in batch mode.
provethemto re-prove libraries (collection of theories) in batch mode.
