SYNOPSIS
proveit <option> ... <dir> | <file>[.pvs] | [<ctxt>]@<thf1>,..,<thfn> ...
where <thfi> has the form <th>[.<f1>:..:<fm>]
DESCRIPTION
If directory <dir> is provided, prove all theories imported in
<dir>/top.pvs. If a PVS <file> is provided, prove all theories
defined in it. The proof status is saved in the working directory in
a file that can be specified using the option -out. Otherwise, a
default name of the form <dir>$EXT or <file>$EXT is used depending
on the given options.
TYPICAL USE
* If <dir> is a library, e.g., there is a file <dir>/top.pvs that
imports all other theories in <dir>, then type: \$proveit <dir>
* If <file>.pvs is a regular PVS file, then type: \$proveit <file>
* If <file>.pvs is a regular PVS file and want to reprove all
formulas, including those in imported files, then type:
\$proveit -a <file>
ADVANCED USE
In the more general form, a context, a list of theories, and a list of
formulas are specified using the syntax <[ctxt]@thf1,..,thfn>, where <ctxt>
is a directory and each <thfi> has the form <th[.f1:..:fm]> with <th> being a
theory and <f1:..:fn> a list of formulas in <th>. Only formulas specified
this way are proven by PVS. In this case, the proof status is saved
in <th.f1:..:fm>$EXT in <ctxt>. For example, to prove formulas <f1> and
<f2> in theory <theory> in the current context, type:
\$proveit @<theory>.<f1>:<f2>
OPTIONS
Options are processed in the order they appear. One letter options can be
combined.
-a|--all equivalent to -ciq -p Field
-c|--clean remove bin files and .pvscontext
-C|--clean-only clean but do not typecheck or prove the theory
-d|--dir <dir> use <dir> as default directory of summary files
--dependencies compute theory dependencies and save them in pvsbin/<outfile>.dep.
By default, dependencies are computed when proving a directory
--disable <o1,..,on> disable external oracles o1,...,on
--disable-oracles disable any external oracle
--enable <o1,..,on> enable external oracles o1,..,on. Overwrite --disable
.<ext> use <ext> as default extension of summary files
-f|--force force proof reruns (default)
~f|--no-force don't force proof reruns
-h|--help print this message
-i|--importchain prove chain of imported theories (set --no-scripts)
~i|--no-importchain don't prove chain of imported theories (default)
--lisp <lisp> specify lisp version; <lisp> is one of allegro,cmulisp
-l|--log log all information generated by PVS in <outfile>.log
~l|--no-log don't log PVS information (default)
-o|--out <outfile> save the proof status summary in <outfile>
-p|--prelude-ext <p1,..,pn> load prelude extensions p1,..,pn
~p|--no-prelude-ext don't load any prelude extension
-q|--quiet print only untried and unfinished proofs per theory,
and grand total
-s|--scripts install ProofLite scripts (default)
~s|--no-scripts don't install ProofLite scripts
--tex generate LaTeX proof files in directory pvstex
--no-tex don't generate LaTeX proof files (default)
--txt generate text proof files in directory pvstxt
--no-txt don't generate text proof files (default)
-t|--top <th> use <th>.pvs instead of top.pvs when proving a directory
--traces include proof traces in log file
--no-traces don't include proof traces in log file (default)
-T|--typecheck-only typecheck but do not prove the theory
-v|--verbose print proof status information per theory and grand
total (default)
--version print version information and exit
