NAME

       JACAL - symbolic mathematics system

SYNOPSIS

       jacal [ scheme | scm | gsi | mzscheme | guile | scheme48 | larceny | scmlit | elk | sisc | kawa ]

DESCRIPTION

       JACAL  is  a  symbolic  mathematics  system  for  the simplification and manipulation of equations and single and multiple valued algebraic
       expressions constructed of numbers, variables, radicals, and algebraic functions, differential, and holonomic functions.  In addition, vec-
       tors and matrices of the above objects are included.

OPTIONS

       The optional argument to the jacal script is the Scheme implementation to run.  Absent the argument, it searches for implementations in the
       above order.

ENVIRONMENT VARIABLES

       SCHEME_LIBRARY_PATH
	      is the SLIB Scheme library directory.

FILES

       demo
	      batch("demo"); to demonstrate commands in jacal

       rw.math
	      batch("rw.math"); to demonstrate tensors in "The Robertson-Walker Cosmology Model".

       test.math
	      batch("test.math"); for regression suite.

NAME

       guile - a Scheme interpreter

SYNOPSIS

       guile [-q] [-ds] [--help] [--version] [--emacs] [--debug] [-l FILE] [-e FUNCTION] [] [-c EXPR] [-s SCRIPT] [--]

DESCRIPTION

       GNU  Guile  is  an  interpreter for the Scheme programming language.  It implements R5RS, providing additional features necessary for real-
       world use.  It is extremely simple to embed guile into a C program, calling C from Scheme and Scheme from C.  Guile's design makes it  very
       suitable for use as an "extension" or "glue" language, but it also works well as a stand-alone scheme development environment.

       The guile executable itself provides a stand-alone interpreter for scheme programs, for either interactive use or executing scripts.

       This  manpage  provides	only brief instruction in invoking guile from the command line.  Please consult the guile info documentation (type
       info guile at a command prompt) for more information.  There is also a tutorial (info guile-tut) available.

OPTIONS

       -l     Load scheme source code from file.

       -e     After reading script, apply FUNCTION to command-line arguments

       -ds    do -s SCRIPT at this point (note that this argument must be used in conjuction with -s)

       --help Describe command line options and exit

       --debug
	      Start guile with debugging evaluator and backtraces enabled (useful for debugging guile scripts)

       --version
	      Display guile version and exit.

       --emacs
	      Enable emacs protocol for use from within emacs (experimental)

       --     Stop argument processing, start guile in interactive mode.

       -c     Stop argument processing, evaluate EXPR as a scheme expression.

       -s     Load Scheme source from SCRIPT-FILE and execute as a script.

ENVIRONMENT

       GUILE_LOAD_PATH
	      If $GUILE_LOAD_PATH is set, its value is used to agument the path to search for scheme files when loading.  It  should  be  a  colon
	      separated list of directories which will be prepended to the default %load-path.

FILES

       ~/.guile  is a guile script that is executed before any other processing occurs.  For example, the following .guile activates guile's read-
       line interface:

	   (use-modules (ice-9 readline))
	   (activate-readline)

SEE ALSO

       The full documentation for guile is maintained as a Texinfo manual.  If the info and guile programs are properly installed  at  your  site,
       the command

	      info guile

       should give you access to the complete manual.

       http://www.schemers.org provides a general introduction to the Scheme language.

       guile is GNU software.  Guile is originally based on Aubrey Jaffer's SCM interpreter, and is the work of many individuals.
