Please send Guile bug reports to bug-guile@gnu.org.
Changes in 2.0.1 (since 2.0.0):
* New procedures (see the manual for details)
** exact-integer-sqrt, imported into core from (rnrs base)
* Bugs fixed
** exact-integer-sqrt now handles large integers correctly
exact-integer-sqrt now works correctly when applied to very large
integers (too large to be precisely represented by a C double).
It has also been imported into core from (rnrs base).
Changes in 2.0.0 (changes since the 1.8.x series):
* New modules (see the manual for details)

!!! This is not a Guile release; it is a source tree retrieved via
Git or as a nightly snapshot at some random time after the
Guile 1.8 release. If this were a Guile release, you would not see
this message. !!! [fixme: zonk on release]
This is a 1.9 development version of Guile, Project GNU's extension
language library. Guile is an interpreter for Scheme, packaged as a
library that you can link into your applications to give them their
own scripting language. Guile will eventually support other languages
as well, giving users of Guile-based applications a choice of
languages.
Guile versions with an odd middle number, i.e. 1.9.* are unstable
development versions. Even middle numbers indicate stable versions.
This has been the case since the 1.3.* series.
The next stable release will likely be version 2.0.0.
This is version 2.0 of Guile, Project GNU's extension language library.
Guile is an implementation of the Scheme programming language, packaged
as a library that can be linked into applications to give them their own
extension language. Guile supports other languages as well, giving
users of Guile-based applications a choice of languages.

## Commentary:
## This fragment defines two variables: preinstguile, preinstguiletool.
## It can be included in any Makefile.am by adding the line:
## include $(top_srcdir)/am/pre-inst-guile
## See devel/build/pre-inst-guile.text (CVS only) for more info.
## Code:
preinstguile = $(top_builddir_absolute)/meta/guile
preinstguiletool = GUILE="$(preinstguile)" $(top_srcdir)/scripts
## am/pre-inst-guile ends here

.SH DESCRIPTION
GNU Guile is an implemention 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 applications, as well as
for stand-alone Scheme application development.
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 applications,
as well as for stand-alone Scheme application development.
The
.B 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.
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
.B guile
from the command line. Please consult the guile info documentation
(type
.B info "guile(Invoking Guile)"
at a command prompt) for more information.
from the command line.
Please consult the Guile info documentation for more information,
(type \fB info "(guile)Invoking Guile"\fR at a command prompt).
.
.SH OPTIONS
.IP -L DIRECTORY
Add DIRECTORY to the front of Guile's module load path.
.IP -l FILE
Load scheme source code from file.
.IP -e FUNCTION
After reading script, apply FUNCTION to command-line arguments. Note
that FUNCTION is evaluated, so e.g.
.TP
.BI -L \ DIRECTORY
Add \fIDIRECTORY\fR to the front of Guile's module load path.
.
.TP
.BI -l \ FILE
Load Scheme source code from \fIFILE\fR.
.
.TP
.BI -e \ FUNCTION
After reading \fISCRIPT\fR, apply \fIFUNCTION\fR to command-line arguments.
Note that \fIFUNCTION\fR is evaluated,
so, for example,
.B (@ (my-module) my-proc)
is valid here.
.IP \\\\
.
.TP
.B \e
The "meta switch", used to work around limitations in #! scripts.
See "The Meta Switch" in the texinfo documentation, for more details.
.IP --
Stop argument processing, start guile in interactive mode.
.IP -c EXPR
Stop argument processing, evaluate EXPR as a scheme expression.
.IP -s SCRIPT-FILE
Load Scheme source from SCRIPT-FILE and execute as a script. Note that
the in many cases it is not necessary to use -s; one may invoke Guile
just as
.B guile SCRIPT-FILE ARG...
.IP -ds
Do -s SCRIPT at this point. Note that this argument must be used in
conjuction with -s.
.IP --debug
Start guile with the debugging VM. By default, on when invoked
interactively, off otherwise.
.IP --auto-compile
See "The Meta Switch" in the texinfo documentation for more details.
.
.TP
.B --
Stop argument processing, and start
.B guile
in interactive mode.
.
.TP
.BI -c \ EXPR
Stop argument processing,
and evaluate \fIEXPR\fR as a Scheme expression.
.
.TP
.BI -s \ SCRIPT-FILE
Load Scheme source from \fISCRIPT-FILE\fR and execute as a script.
Note that in many cases it is not necessary to use \fB-s\fR;
one may invoke
.B guile
simply as
.B guile
.I SCRIPT-FILE ARG...
.
.TP
.B -ds
Carry out \fB\-s \fISCRIPT\fR at this point in the option sequence.
Note that this argument must be used in conjunction with \fB\-s\fR.
.
.TP
.B --debug
Start
.B guile
with the debugging VM.
By default, debugging is on when
.B guile
is invoked interactively;
it is off otherwise.
.
.TP
.B --no-debug
Start
.B guile
without the debugging VM,
even if
.B guile
is being run interactively.
.
.TP
.B --auto-compile
Compile source files automatically (default behavior).
.IP --no-auto-compile
.
.TP
.B --no-autocompile
Disable automatic source file compilation.
.IP --listen[=P]
Listen on a port or socket for remote REPL connections. See the manual
for more details.
.IP --use-srfi=N,M...
Load SRFI extensions N, M, etc. For example, "--use-srfi=8,13".
.IP -x EXTENSION
Add EXTENSION to the Guile's load extension list.
.IP --help
Describe command line options and exit
.IP --version
.
.TP
\fB\-\-listen\fR[=\fIP\fR]
Listen on a port or socket for remote REPL connections.
See the manual for more details.
.
.TP
\fB\-\-use\-srfi\fR=\fIN,M\fR...
Load SRFI extensions \fIN\fR, \fIM\fR, etc.
For example,
\fB \-\-use\-srfi\fR=\fI8,13\fR.
.
.TP
.BI -x \ EXTENSION
Add \fIEXTENSION\fR to the
.B guile
load extension list.
.
.TP
\fB\-h\fR, \fB\-\-help\fR
Describe command-line options and exit.
.
.TP
\fB\-v\fR, \fB\-\-version\fR
Display guile version and exit.
.IP -q
In interactive mode, suppress loading the user's ~/.guile file.
.
.TP
.B -q
In interactive mode,
suppress loading the user's initialization file,
.I ~/.guile.

@node Inlinable Procedures
@subsection Inlinable Procedures
You can define an @dfn{inlinable procedure} by using
@code{define-inlinable} instead of @code{define}. An inlinable
procedure behaves the same as a regular procedure, but direct calls will
result in the procedure body being inlined into the caller.
Procedures defined with @code{define-inlinable} are @emph{always}
inlined, at all direct call sites. This eliminates function call
overhead at the expense of an increase in code size. Additionally, the
caller will not transparently use the new definition if the inline
procedure is redefined. It is not possible to trace an inlined
procedures or install a breakpoint in it (@pxref{Traps}). For these
reasons, you should not make a procedure inlinable unless it
demonstrably improves performance in a crucial way.
In general, only small procedures should be considered for inlining, as
making large procedures inlinable will probably result in an increase in
code size. Additionally, the elimination of the call overhead rarely
matters for for large procedures.

manual. Once you've compiled your source files, you need to link them
against the Guile object code library, @code{libguile}.
On most systems, you should not need to tell the compiler and linker
explicitly where they can find @file{libguile.h} and @file{libguile}.
When Guile has been installed in a peculiar way, or when you are on a
peculiar system, things might not be so easy and you might need to pass
additional @code{-I} or @code{-L} options to the compiler. Guile
provides the utility program @code{guile-config} to help you find the
right values for these options. You would typically run
@code{guile-config} during the configuration phase of your program and
@code{<libguile.h>} is not in the default search path for headers,
because Guile supports parallel installation of multiple versions of
Guile, with each version's headers under their own directories. This is
to allow development against, say, both Guile 2.0 and 2.2.
To compile code that includes @code{<libguile.h>}, or links to
@code{libguile}, you need to select the effective version you are
interested in, and then ask @code{pkg-config} for the compilation flags
or linking instructions. For effective version
@value{EFFECTIVE-VERSION}, for example, you would invoke
@code{pkg-config --cflags --libs guile-@value{EFFECTIVE-VERSION}} to get
the compilation and linking flags necessary to link to version
@value{EFFECTIVE-VERSION} of Guile. You would typically run
@code{pkg-config} during the configuration phase of your program and
use the obtained information in the Makefile.
