NAME

   cafeobj - algebraic specification and programming language

SYNOPSIS

   cafeobj [OPTION]... [FILES]...

DESCRIPTION

   Starts the CafeOBJ interpreter.

   CafeOBJ is a most advanced formal specification language which inherits
   many advanced features (e.g.  flexible  mix-fix  syntax,  powerful  and
   clear  typing  system with ordered sorts, parameteric modules and views
   for instantiating the parameters, and module  expressions,  etc.)  from
   OBJ (or more exactly OBJ3) algebraic specification language.

   CafeOBJ   is   a   language  for  writing  formal  (i.e.  mathematical)
   specifications of models for wide varieties of  software  and  systems,
   and  verifying  properties of them. CafeOBJ implements equational logic
   by rewriting and can be used as a powerful interactive theorem  proving
   system.  Specifiers  can  write  proof scores also in CafeOBJ and doing
   proofs by executing the proof scores.

   CafeOBJ  has  state-of-art  rigorous   logical   semantics   based   on
   institutions.  The  CafeOBJ  cube  shows  the  structure of the various
   logics underlying the combination of the various paradigms  implemented
   by  the language. Proof scores in CafeOBJ are also based on institution
   based rigorous semantics, and can be constructed using a  complete  set
   of proof rules.

OPTIONS

   There are two classes of options. The first are options for the cafeobj
   wrapper script  that  allows  to  select  the  underlying  Common  Lisp
   interpreter, and to adjust search path parameters.

   -engine NAME
          selects  the  underlying  common  lisp engine. If not given, the
          first one selected during build time is used.

   -list-engines
          lists all available common lisp engines

   -wrapper-libpath PATH
          sets the path where memory dumps of the  lisp  interpreters  are
          found

   -wrapper-sharepath PATH
          sets the path where CafeOBJ initialization files are searched

   The  following  set  of options are directed at the CafeOBJ interpreter
   directly:

   -help  print a help message

   -q     do not load user's initialization file

   -batch run in batch mode

   -p PATH
          gives the standard prelude file defining modules

   +p PATH
          load additional prelude file

   -l DIR-LIST
          set list of pathnames  for  module  search  path,  separated  by
          colons

   +l DIR-LIST
          adds a list of pathname for module search path

   FILES  files that are loaded at startup time in order.

Opportunity


Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.

Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.



Free Software


Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.

Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.



Free Books


The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.

Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.



Education


Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.

Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
