The Itp Tool's Manual *

The ITP tool is an experimental inductive theorem prover for proving properties of Maude equational specifications, i.e., specifications in membership equational logic with an initial algebra semantics. The ITP tool has been written entirely in Maude and is in fact an executable specification of the formal inference system that it implements. 1 Getting started To run the current version of the ITP you need to have installed the latest version of the Maude system (version 2.1.1) in your computer. You can download the latest version of Maude from the Maude’s home page: http://maude.cs.uiuc.edu. The current version of the ITP is distributed as the gzip-tar-file itp-tool-vxxx.tar.gz (where xxx is the actual version identifier), which is available at http://maude.sip.ucm. es/itp. To untar this file, type tar xvfz itp-tool-vxxx.tar.gz. This command will create a directory itp-tool-vxxx with a subdirectory itp-src containing the ITP tool’s source files: bash>tar xvfz itp-tool-vxxx.tar.gz itp-tool-vxxx/ itp-tool-vxxx/itp-src/ itp-tool-vxxx/itp-src/unification.maude itp-tool-vxxx/itp-src/basic.maude itp-tool-vxxx/itp-src/check.maude itp-tool-vxxx/itp-src/ext-mod.maude itp-tool-vxxx/itp-src/ext-term.maude itp-tool-vxxx/itp-src/itp-tool.maude bash> 2 Understanding the ITP Mechanical reasoning about functional modules in Maude is supported by the experimental ITP tool, a rewriting-based theorem prover that can be used to prove inductive properties of membership equational specifications. It is written in Maude, and it is itself an executable ∗Research supported by Spanish MCYT projects TIC2002-01167 and TIC2003-01000.
