ProofLite scripts can be created from proofs in two ways: (1) Place the cursor on the formula for which you want to create a ProofLite script and issue the Emacs command: M-x insert-prooflite-script (C-c 2p). T he ProofLite script is automatically inserted after the formula. (2) Issue the command: M-x display-prooflite-script (C-c dp) and enter the name of a formula. The ProofLite script of that formula is displayed in the buffer “ProofLite”.

• Introduce all types in formula: (all-typepreds)
• (typepred a b c)
