NAME
       guile - The GNU Project Extension Language

SYNOPSIS
       guile  [-L  DIRECTORY]  [-l  FILE]  [-e	FUNCTION]  [\] [-c EXPR] [-s SCRIPT] [--] [SCRIPT
       [ARGs for SCRIPT]]

       Only the most useful options are listed here; see below for the remainder.

DESCRIPTION
       GNU Guile is an implementation of the Scheme programming language.  It  extends	the  R5RS
       and R6RS language standards, providing additional features necessary for real-world use.

       Guile  works  well  for interactive use, basic scripting, and extension of larger applica-
       tions, as well as for stand-alone Scheme application development.

       The guile executable itself provides a stand-alone interactive compiler and  run-time  for
       Scheme programs, both for interactive use and for executing Scheme scripts or programs.

       This  manual page provides only brief instruction in invoking guile from the command line.
       Please  consult	the  Guile  info  documentation  for  more   information,   (type    info
       "(guile)Invoking Guile" at a command prompt).

OPTIONS
       -L DIRECTORY
	      Add DIRECTORY to the front of Guile's module load path.

       -l FILE
	      Load Scheme source code from FILE.

       -e FUNCTION
	      After reading SCRIPT, apply FUNCTION to command-line arguments.  Note that FUNCTION
	      is evaluated, so, for example, (@ (my-module) my-proc) is valid here.

       \      The "meta switch", used to work around limitations in #! scripts.   See  "The  Meta
	      Switch" in the texinfo documentation for more details.

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

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

       -s SCRIPT-FILE
	      Load  Scheme  source  from  SCRIPT-FILE and execute as a script.	Note that in many
	      cases it is not necessary to use -s; one may invoke guile simply as  guile  SCRIPT-
	      FILE ARG...

       -ds    Carry  out -s SCRIPT at this point in the option sequence.  Note that this argument
	      must be used in conjunction with -s.

       --debug
	      Start guile with the debugging VM.  By default,  debugging  is  on  when	guile  is
	      invoked interactively; it is off otherwise.

       --no-debug
	      Start guile without the debugging VM, even if guile is being run interactively.

       --auto-compile
	      Compile source files automatically (default behavior).

       --no-autocompile
	      Disable automatic source file compilation.

       --listen[=P]
	      Listen  on  a  port or socket for remote REPL connections.  See the manual for more
	      details.

       --use-srfi=N,M...
	      Load SRFI extensions N, M, etc.  For example,
	       --use-srfi=8,13.

       -x EXTENSION
	      Add EXTENSION to the guile load extension list.

       -h, --help
	      Describe command-line options and exit.

       -v, --version
	      Display guile version and exit.

       -q     In interactive mode, suppress loading the user's initialization file, ~/.guile.

ENVIRONMENT
       GUILE_LOAD_PATH
	      If $GUILE_LOAD_PATH is set before guile is started, its value is	used  to  augment
	      the  path  to search for Scheme files when loading.  It should be a colon-separated
	      list of directories, which will be prefixed to the default %load-path.

       GUILE_LOAD_COMPILED_PATH
	      If $GUILE_LOAD_COMPILED_PATH is set before guile is started, its value is  used  to
	      augment  the path to search for compiled Scheme files (.go files) when loading.  It
	      should be a colon-separated list of directories, which  will  be	prefixed  to  the
	      default %load-compiled-path.

FILES
       ~/.guile
	      A  Guile	script that is executed before any other processing occurs.  For example,
	      the following .guile activates guile's readline 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.

REPORTING BUGS
       There  is  a  mailing  list,  bug-guile@gnu.org,  for reporting Guile bugs and fixes.  But
       before reporting something as a bug, please try to be sure that it really is a bug, not	a
       misunderstanding  or  a	deliberate  feature.   We ask you to read the section ``Reporting
       Bugs'' in the Guile reference manual (or Info system) for hints on how and when to  report
       bugs.   Also,  include the version number of the Guile you are running in every bug report
       that you send in.  Bugs tend actually to get fixed if they can be isolated, so  it  is  in
       your interest to report them in such a way that they can be easily reproduced.
