+The software in this package is distributed under the GNU General Public
+License (with a special exception described below as 13th term).
+
+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ 13. Linking this library statically or dynamically with other modules is making a combined work based on this library. Thus, the terms and conditions of the GNU General Public License cover the whole combination.
+
+As a special exception, the copyright holders of this software give you
+permission to link this software with independent modules to produce an
+executable, regardless of the license terms of these independent modules, and
+to copy and distribute the resulting executable under terms of your choice,
+provided that you also meet, for each linked independent module, the terms and
+conditions of the license of that module. An independent module is a module
+which is not derived from or based on this software. If you modify this
+software, you may extend this exception to your version of the software, but
+you are not obligated to do so. If you do not wish to do so, delete this
+exception statement from your version.
+
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>

+GENERAL INFORMATION
+===================
+
+Armed Bear Common Lisp is an implementation of ANSI Common Lisp that
+runs in a Java virtual machine. It compiles its code to Java byte code.

+
+
+BUILDING
+========
+
+If you want to build ABCL, you have 3 options. The first option
+applies when you come from a lisp background. The second and thirds
+options are more appropriate when you come from Java development:
+
+ I) Bootstrap ABCL using a Common Lisp implementation
+ Supported implementations for this process: SBCL, CMUCL, OpenMCL,
+ Allegro CL, LispWorks or CLISP.
+
+II) Use the Ant make-like build tool for Java environments
+ The tested lowest working version is Ant 1.7.0.
+
+III) Use the Netbeans 6.x IDE to open ABCL as a project.
+
+
+In both cases you need a supported JDK version (1.5 and 1.6 have been
+tested). Just the JRE isn't enough.
+
+
+
+I. Lisp-based build
+-------------------
+
+Copy the file 'customizations.lisp.in' to customization.lisp', in the
+directory containing this README file, editing to suit your situation,
+paying attention to the comments in the file.
+
+Start up one of the supported Common Lisp implementations in the
+directory containing this README file.
+
+Load build-abcl.lisp:
+
+ (load "build-abcl.lisp")
+
+Then do:
+
+ (build-abcl:build-abcl :clean t :full t)
+
+Wait for the build to finish and exit the host Lisp.
+
+Use abcl.bat on Windows or ./abcl on Unix to start ABCL.
+Note: abcl.bat and abcl contain absolute paths, so you'll need
+to edit them if you move things around after the build.
+
+In case of failure in the javac stage, you might try this:
+
+ (build-abcl:build-abcl :clean t :full t :batch nil)
+
+This invokes javac separately for each .java file, which avoids running
+into limitations on command line length (but is a lot slower).
+
+
+II. Ant-based build
+-------------------
+
+With Ant in your path, executing
+
+ ant -find build.xml abcl.wrapper
+
+from the directory containing this README file will create an
+executable wrapper ('abcl' under UNIX, 'abcl.bat' under Windows).
+Use this wrapper to start the ABCL Java program.
+
+
+III. Netbeans-based build
+-------------------------
+
+One should be able to open the project as a project in Netbeans 6.x.
+
+
+BUGS
+====
+
+A lot of (renewed) energy has been spent to make ABCL a compliant
+and practically useable Common Lisp implementation. Because of this,
+ABCL 0.0.11 now fails only 47 out of 21702 tests in the ANSI CL test
+suite. Next to that, the fail count of the Maxima test suite has been
+reduced from over 1400 in 0.0.10 to little more than 600 in 0.0.11.
+
+ABCL's CLOS does not handle on-the-fly redefinition of classes
+correctly, and in any event is intolerably slow. There is no support
+for the long form of DEFINE-METHOD-COMBINATION, and certain other
+required CLOS features are also missing. Enough CLOS is there to run
+ASDF and CL-PPCRE, if you're in no hurry.
+
+There is no MOP worth mentioning.
+
+Since this is a early public release, there might be build
+problems as well as runtime bugs.
+
+Please report problems to the j-devel mailing list:
+
+ armedbear-j-devel at lists.sourceforge.net
+
+Have fun!
+
+On behalf of all ABCL development team and contributors,
+Erik Huelsmann

+ABCL Examples Building and Running Instructions
+===============================================
+
+code by Ville Voutilainen
+instructions by Blake McBride
+updated by Mark Evenson
+
+In general, to compile a Java class file (like Main.java for example
+in the 'java_exception_in_lisp' subdirectory) use:
+
+ cmd$ cd java_exception_in_lisp
+ cmd$ javac -cp ../../../dist/abcl.jar Main.java
+
+where the "../../../dist/abcl.jar" represents the path to your
+abcl.jar file, which is built via the Ant based build. This path
+could be slightly different depending on how the system was
+constructed, and possibly due to operating system conventions for
+specifying relative paths. However you resolve this locally, we'll
+refer to this as '$ABCL_ROOT/dist/abcl.jar' for the rest of these
+instructions.
+
+This compiles the Java source file "Main.java" into a JVM runtime or
+class file named "Main.class".
+
+To run the example (Main.class for example) from a Unix-like OS use:
+
+ cmd$ java -cp $ABCL_ROOT/dist/abcl.jar:. Main
+
+or in Windows use:
+
+ cmd$ java -cp $ABCL_ROOT/dist/abcl.jar;. Main
+
+where "Main" is the initial class to run in your Java program.

+
+;;; FLONUM-TO-STRING (and its subsidiary function FLOAT-STRING) does
+;;; most of the work for all printing of floating point numbers in the
+;;; printer and in FORMAT. It converts a floating point number to a
+;;; string in a free or fixed format with no exponent. The
+;;; interpretation of the arguments is as follows:
+;;;
+;;; X - The floating point number to convert, which must not be
+;;; negative.
+;;; WIDTH - The preferred field width, used to determine the number
+;;; of fraction digits to produce if the FDIGITS parameter
+;;; is unspecified or NIL. If the non-fraction digits and the
+;;; decimal point alone exceed this width, no fraction digits
+;;; will be produced unless a non-NIL value of FDIGITS has been
+;;; specified. Field overflow is not considerd an error at this
+;;; level.
+;;; FDIGITS - The number of fractional digits to produce. Insignificant
+;;; trailing zeroes may be introduced as needed. May be
+;;; unspecified or NIL, in which case as many digits as possible
+;;; are generated, subject to the constraint that there are no
+;;; trailing zeroes.
+;;; SCALE - If this parameter is specified or non-NIL, then the number
+;;; printed is (* x (expt 10 scale)). This scaling is exact,
+;;; and cannot lose precision.
+;;; FMIN - This parameter, if specified or non-NIL, is the minimum
+;;; number of fraction digits which will be produced, regardless
+;;; of the value of WIDTH or FDIGITS. This feature is used by
+;;; the ~E format directive to prevent complete loss of
+;;; significance in the printed value due to a bogus choice of
+;;; scale factor.
+;;;
+;;; Most of the optional arguments are for the benefit for FORMAT and are not
+;;; used by the printer.
+;;;
+;;; Returns:
+;;; (VALUES DIGIT-STRING DIGIT-LENGTH LEADING-POINT TRAILING-POINT DECPNT)
+;;; where the results have the following interpretation:
+;;;
+;;; DIGIT-STRING - The decimal representation of X, with decimal point.
+;;; DIGIT-LENGTH - The length of the string DIGIT-STRING.
+;;; LEADING-POINT - True if the first character of DIGIT-STRING is the
+;;; decimal point.
+;;; TRAILING-POINT - True if the last character of DIGIT-STRING is the
+;;; decimal point.
+;;; POINT-POS - The position of the digit preceding the decimal
+;;; point. Zero indicates point before first digit.
+;;;
+;;; NOTE: FLONUM-TO-STRING goes to a lot of trouble to guarantee
+;;; accuracy. Specifically, the decimal number printed is the closest
+;;; possible approximation to the true value of the binary number to
+;;; be printed from among all decimal representations with the same
+;;; number of digits. In free-format output, i.e. with the number of
+;;; digits unconstrained, it is guaranteed that all the information is
+;;; preserved, so that a properly- rounding reader can reconstruct the
+;;; original binary number, bit-for-bit, from its printed decimal
+;;; representation. Furthermore, only as many digits as necessary to
+;;; satisfy this condition will be printed.
+;;;
+;;; FLOAT-STRING actually generates the digits for positive numbers.
+;;; The algorithm is essentially that of algorithm Dragon4 in "How to
+;;; Print Floating-Point Numbers Accurately" by Steele and White. The
+;;; current (draft) version of this paper may be found in
+;;; [CMUC]<steele>tradix.press. DO NOT EVEN THINK OF ATTEMPTING TO
+;;; UNDERSTAND THIS CODE WITHOUT READING THE PAPER!

+;;;;
+;;;; Notes
+;;;; =====
+;;;; A simple implementation of Gray streams for Corman Lisp 1.42.
+;;;; Gray streams are 'clos' based streams as described at:
+;;;;
+;;;; ftp://parcftp.xerox.com/pub/cl/cleanup/mail/stream-definition-by-user.mail
+;;;;
+;;;; Some differences exist between this implementation and the
+;;;; specification above. See notes below for details.
+;;;;
+;;;; More recent versions of this software may be available at:
+;;;; http://www.double.co.nz/cl
+;;;;
+;;;; Comments, suggestions and bug reports to the author,
+;;;; Christopher Double, at: chris at double.co.nz
+;;;;
+;;;; 03/03/2001 - 1.0
+;;;; Initial release.
+;;;;
+;;;; 20/08/2001 - 1.1
+;;;; Small modifications by Frederic Bastenaire (fba at free.fr)
+;;;; (lines flagged by ;; # fb 1.01)
+;;;; - Make it work with the READ function by
+;;;; defining %read-char, %read-char-with-error
+;;;; and input-character-stream-p
+;;;; - Add nickname GS to package "GRAY-STREAMS" for ease of use
+;;;; - added missing '*' to *old-write-byte* in gray-write-byte
+;;;;
+;;;; 03/01/2002 - 1.2
+;;;; Fixed bug with GRAY-WRITE-LINE and GRAY-WRITE-STRING
+;;;; that appeared in Corman Lisp 2.0 due to changes to
+;;;; WRITE-LINE and WRITE-STRING.
+;;;;
+;;;; 04/01/2002 - 1.3
+;;;; Added support for STREAM-READ-SEQUENCE and STREAM-WRITE-SEQUENCE.
+;;;; Fixed STREAM-WRITE-STRING bug.
+;;;;
+;;;; Notes
+;;;; =====
+;;;; CLOSE is not a generic function in this implementation. Instead,
+;;;; the generic is called STREAM-CLOSE and the function CLOSE calls
+;;;; STREAM-CLOSE. The same goes for STREAMP, INPUT-STREAM-P,
+;;;; OUTPUT-STREAM-P and STREAM-ELEMENT-TYPE. The generic functions for
+;;;; these are STREAM-STREAMP, STREAM-INPUT-STREAM-P,
+;;;; STREAM-OUTPUT-STREAM-P and STREAM-STREAM-ELEMENT-TYPE.
+;;;;
+;;;; The standard Corman Lisp streams are not derived from
+;;;; FUNDAMENTAL-STREAM. All the stream functions check to see if the
+;;;; stream is an original Corman Lisp stream and forward on to the
+;;;; original function implementations.
+;;;;
+;;;; The string streams are implemented in this file as Gray streams
+;;;; but do not replace the Corman Lisp string streams. They are only
+;;;; implemented here to test the Gray stream functionality. These methods
+;;;; are called:
+;;;; GRAY-MAKE-STRING-OUTPUT-STREAM
+;;;; GRAY-GET-OUTPUT-STREAM-STRING
+;;;; GRAY-MAKE-STRING-INPUT-STREAM
+;;;;
+;;;; Much of the implementation of the Gray streams below is from the
+;;;; document referenced earlier.

+(in-package "LOOP")
+
+;;;; The design of this LOOP is intended to permit, using mostly the same
+;;;; kernel of code, up to three different "loop" macros:
+;;;;
+;;;; (1) The unextended, unextensible ANSI standard LOOP;
+;;;;
+;;;; (2) A clean "superset" extension of the ANSI LOOP which provides
+;;;; functionality similar to that of the old LOOP, but "in the style of"
+;;;; the ANSI LOOP. For instance, user-definable iteration paths, with a
+;;;; somewhat cleaned-up interface.
+;;;;
+;;;; (3) Extensions provided in another file which can make this LOOP
+;;;; kernel behave largely compatibly with the Genera-vintage LOOP macro,
+;;;; with only a small addition of code (instead of two whole, separate,
+;;;; LOOP macros).
+;;;;
+;;;; Each of the above three LOOP variations can coexist in the same LISP
+;;;; environment.
+;;;;
+;;;; KLUDGE: In SBCL, we only really use variant (1), and any generality
+;;;; for the other variants is wasted. -- WHN 20000121
+
+;;;; FIXME: the STEP-FUNCTION stuff in the code seems to've been
+;;;; intended to support code which was conditionalized with
+;;;; LOOP-PREFER-POP (not true on CMU CL) and which has since been
+;;;; removed. Thus, STEP-FUNCTION stuff could probably be removed too.

+The basic idea of all this minimax randomness here is that we have to
+have constructed all uses of maximize and minimize to a particular
+"destination" before we can decide how to code them. The goal is to not
+have to have any kinds of flags, by knowing both that (1) the type is
+something which we can provide an initial minimum or maximum value for
+and (2) know that a MAXIMIZE and MINIMIZE are not being combined.
+
+SO, we have a datastructure which we annotate with all sorts of things,
+incrementally updating it as we generate loop body code, and then use
+a wrapper and internal macros to do the coding when the loop has been
+constructed.

+ <dd>
+ Armed Bear Common Lisp (ABCL) is an implementation of ANSI Common Lisp
+ that runs in a Java virtual machine. It provides a runtime system, a
+ compiler that compiles Lisp source to JVM bytecode, and an interactive
+ REPL for program development.
+ <p>
+ ABCL is distributed under the terms of the <a href="http://www.gnu.org/copyleft/gpl.html">GNU General Public
+ License</a>, with a special linking exception. If you link ABCL with your
+ own program, then you do not need to release the source code for that
+ program. However, any changes that you make to ABCL itself must be
+ released in accordance with the terms of the GPL.
+ <p>
+ ABCL runs on platforms that support Java 1.4 (or later), including Linux,
+ Windows, and Mac OS X.
+ <p>
+ ABCL is free software and comes with ABSOLUTELY NO WARRANTY.
+ <p>
+ The latest version is 0.0.10, released March 6, 2007.

+ ABCL is a young implementation (particularly by Lisp standards). You
+ are certain to encounter bugs.
+ <p>
+ ABCL 0.0.10 fails 67 out of 21696 tests in the GCL ANSI test suite.
+ <p>
+ ABCL's CLOS is intolerably slow and does not handle on-the-fly
+ redefinition of classes correctly. There is no support for the long
+ form of DEFINE-METHOD-COMBINATION, and certain other required CLOS
+ features are also missing. Enough CLOS is there to run ASDF and
+ CL-PPCRE, if you're in no hurry. There's no MOP worth mentioning.
+ <p>
+ Since this is an early public release, there might be build problems as
+ well as runtime bugs.

+<dl>
+ <dd>
+ <b>Sep 24 2004 4:45 PM - Version 0.21.0</b>
+ <p>
+ Some minor problems that prevented j from working correctly with the Java 1.5
+ betas are fixed in this release.
+ <p>
+ It is now possible to use drag/drop in the sidebar buffer list to reorder the
+ buffers, so that navigating between buffers using
+ <a href="http://armedbear-j.sourceforge.net/doc/commands.html#nextBuffer">nextBuffer</a> and
+ <a href="http://armedbear-j.sourceforge.net/doc/commands.html#prevBuffer">prevBuffer</a> (mapped by default to
+ Alt Right and Alt Left, respectively) is more efficient. Thanks to Mike
+ Rutter for providing the code to do this.
+ <p>
+ By request, the command
+ <a href="http://armedbear-j.sourceforge.net/doc/commands.html#wrapParagraphsInRegion">wrapParagraphsInRegion</a>
+ has been added. It is mapped by default to Ctrl Shift F12 in plain text and
+ mail composition buffers.
+ <a href="http://armedbear-j.sourceforge.net/doc/commands.html#wrapParagraphsInRegion">wrapParagraphsInRegion</a>
+ walks through the region (or the whole buffer if no region is selected) and,
+ in effect, calls <a href="http://armedbear-j.sourceforge.net/doc/commands.html#wrapParagraph">wrapParagraph</a>
+ on each paragraph.
+ <p>
+ The wrap commands should now do a better job of handling lines that break on
+ the hyphen of a hyphenated word (like "wrap-paragraph"). If the paragraph is
+ subsequently reformatted in such a way that the line break no longer falls on
+ the hyphen in question, the parts of the hyphenated word are now put back
+ together properly. In previous versions of j, you were likely to end up with
+ "wrap- paragraph", with a bogus extra space after the hyphen.
+ <p>
+ The commands
+ <a href="http://armedbear-j.sourceforge.net/doc/commands.html#pageUpOtherWindow">pageUpOtherWindow</a> and
+ <a href="http://armedbear-j.sourceforge.net/doc/commands.html#pageDownOtherWindow">pageDownOtherWindow</a> have
+ been added. They are mapped by default to Alt Page Down and Alt Page Up,
+ respectively, in all modes. These commands are helpful in a split-window
+ situation when you want to scroll the other window without switching to it.
+ <p>
+ The commmand
+ <a href="http://armedbear-j.sourceforge.net/doc/commands.html#findOccurrenceAtDotAndKillList">findOccurrenceAtDotAndKillList</a>
+ has been added. It is mapped by default to Ctrl Enter in List Occurrences
+ buffers. It works like
+ <a href="http://armedbear-j.sourceforge.net/doc/commands.html#findOccurrenceAtDot">findOccurrenceAtDot</a>, but
+ in addition it closes the List Occurrences buffer.
+ <p>
+ The commands <a href="http://armedbear-j.sourceforge.net/doc/commands.html#shellNextPrompt">shellNextPrompt</a>
+ and <a href="http://armedbear-j.sourceforge.net/doc/commands.html#shellPreviousPrompt">shellPreviousPrompt</a>
+ have been added. They are mapped by default to Ctrl Alt N and Ctrl Alt P,
+ respectively, in shell buffers and their derivatives (including Lisp shells),
+ and they help you find the next or previous prompt, starting from the current
+ location of the caret.
+ <p>
+ The command <a href="http://armedbear-j.sourceforge.net/doc/commands.html#p4Log">p4Log</a> has been added. It
+ runs the Perforce command "filelog -l" on the file associated with the
+ current buffer.
+ <p>
+ The command <a href="http://armedbear-j.sourceforge.net/doc/commands.html#p4Diff">p4Diff</a> now runs the
+ Perforce command "p4 diff -f -du", instead of "p4 diff -du". This change
+ means that <a href="http://armedbear-j.sourceforge.net/doc/commands.html#p4Diff">p4Diff</a> will display
+ potentially useful output even if the file associated with the current buffer
+ has not, in Perforce's opinion, been officially opened for editing.
+ <p>
+ J's ssh-related code now recognizes "Response:" as a password prompt, in
+ addition the to other password prompts it recognized already.
+ <p>
+ Compilation buffers are now supported on Windows NT 4. Thanks to Pete Kirkham
+ for pointing out that this was possible.
+ <p>
+ In previous versions of j, there was an incorrect optimization in the display
+ code which malfunctioned on very rare occasions and caused lines to disappear
+ from the display, even though they were still present in the buffer (there
+ was never any loss of data). This bug has been fixed by removing the
+ optimization in question.
+ <p>
+ There are a number of new features and minor improvements in Lisp mode and
+ in Lisp shells. Thanks to Sam Steingold for help with many of these.
+ <p>
+ This release includes version 0.0.4 of Armed Bear Common Lisp. ABCL 0.0.4
+ passes 17778 out of 17942 tests in the GCL ANSI Common Lisp test suite, for a
+ nominal compliance of 99.0859%. The test suite is still not complete,
+ however, so ABCL's actual percentage of ANSI compliance, whatever that may
+ mean, is undoubtedly lower. In any case, version 0.0.4 represents a
+ substantial improvement over version 0.0.3, back when it was still called
+ Armed Bear Lisp, which passed 12986 out of 14127 tests (91.92%).
+ <p>
+ ABCL includes a compiler, written in Lisp, that generates JVM bytecode from
+ Lisp source. The compiler is not finished, and there are valid Lisp
+ constructs that it doesn't know how to compile. In most situations, when the
+ compiler encounters code that it can't compile correctly, it is smart enough
+ to leave the code alone so that it will continue to work correctly with the
+ interpreter. Compiled code and interpreted code can coexist happily in the
+ same running instance of ABCL.
+ <p>
+ The 0.21.0 binary distribution contains a compiled version of the Lisp
+ library code (i.e. a full set of .abcl and .cls files), as well as the Lisp
+ source files for the library code that is implemented in Lisp. If you build j
+ from source, using either configure/make or Ant, the Lisp library code will
+ be compiled as part of the build. There is no longer any need to do
+ COMPILE-SYSTEM manually.
+ <p>
+ ABCL 0.0.4 is better at some things than others. In particular, it's not very
+ good at CLOS. ABCL's CLOS correctness is reasonable, but its CLOS performance
+ is terrible (for one thing, the compiler doesn't even attempt to compile
+ generic functions). This deficiency is due more to simple neglect than to any
+ intrinsic limitation, and the CLOS implementation should improve in future
+ releases.
+ <p>
+ You can start ABCL from within j by doing Alt X, "abcl", or by selecting "Run
+ Lisp as Separate Process" from the Lisp menu. Note that the "Run Embedded
+ Lisp" menu selection opens a Lisp shell using an instance of ABCL that runs
+ in the editor process; it only makes sense to do this if you're planning to
+ interact with the running instance of j, which is not normally the case. If
+ you just want to experiment with ABCL, "Run Lisp as Separate Process" (or Alt
+ X, "abcl") is your friend.
+ <p>
+ If you're truly adventurous, you can also start ABCL from within j by doing
+ Alt X, "slime". J's version of slime is adapted from the "Superior Lisp
+ Interaction Mode for Emacs", originally written by Eric Marsden, Luke Gorrie
+ and Helmut Eller. Slime-for-j is less than a month old, so it is nowhere near
+ as robust or featureful as slime-for-emacs, but in principle it offers more
+ functionality than Alt X, "abcl". In particular, the tab key can be used for
+ symbol completion, function argument lists are displayed in the status bar
+ when you type a space, and Alt . should work to find function definitions (if
+ you've built ABCL from source). In addition, the evaluation of forms and
+ regions in Lisp source files makes an attempt to set *PACKAGE* to the right
+ thing first. I don't think any of these features works 100% correctly yet,
+ but even so, slime-for-j feels like an improvement over the basic Lisp shell
+ functionality available in previous versions of j. For more information, see
+ slime.lisp.
+ <p>
