DESCRIPTIONThis manual page documents briefly the formed command.
formed is a window-based program for constructing, displaying, and managing first-order logic formulas. The main motivation for constructing formed was the desire to have formulas displayed in a readable, two-dimensional format. Users of formed can make two kinds of transformation on formulas: (1) logic transformations, such as negation normal form translation, which preserve the meaning of a formula, and (2) edit transformations, which can be used to make arbitrary changes, such as adding a hypothesis to a subformula. formed was written by using the X Window System, Version 11, and code from the theorem prover otter.
