243 <h2 class="chapter">1 Preface</h2>
245 <p>This manual describes the <a href="http://www.gnu.org/software/guile/">GNU Guile</a> Scheme programming interface to GnuTLS. The reader is
246 assumed to have basic knowledge of the protocol and library. Details
247 missing from this chapter may be found in Function reference,
248 of the C API reference.
250 <p>At this stage, not all the C functions are available from Scheme, but
251 a large subset thereof is available.

260 <h2 class="chapter">2 Guile Preparations</h2>
262 <p>The GnuTLS Guile bindings are available for both the 1.8 and 2.0 stable
265 <p>By default they are installed under the GnuTLS installation directory,
266 typically <samp>/usr/local/share/guile/site/</samp>). Normally Guile
267 will not find the module there without help. You may experience
270 <div class="example">
271 <pre class="example">$ guile
272 guile> (use-modules (gnutls))
273 <unnamed port>: no code for module (gnutls)
277 <p>There are two ways to solve this. The first is to make sure that when
278 building GnuTLS, the Guile bindings will be installed in the same
279 place where Guile looks. You may do this by using the
280 <code>--with-guile-site-dir</code> parameter as follows:
282 <div class="example">
283 <pre class="example">$ ./configure --with-guile-site-dir=no
286 <p>This will instruct GnuTLS to attempt to install the Guile bindings
287 where Guile will look for them. It will use <code>guile-config info
288 pkgdatadir</code> to learn the path to use.
290 <p>If Guile was installed into <code>/usr</code>, you may also install GnuTLS
291 using the same prefix:
293 <div class="example">
294 <pre class="example">$ ./configure --prefix=/usr
297 <p>If you want to specify the path to install the Guile bindings you can
298 also specify the path directly:
300 <div class="example">
301 <pre class="example">$ ./configure --with-guile-site-dir=/opt/guile/share/guile/site
304 <p>The second solution requires some more work but may be easier to use
305 if you do not have system administrator rights to your machine. You
306 need to instruct Guile so that it finds the GnuTLS Guile bindings.
307 Either use the <code>GUILE_LOAD_PATH</code> environment variable as follows:
309 <div class="example">
310 <pre class="example">$ GUILE_LOAD_PATH="/usr/local/share/guile/site:$GUILE_LOAD_PATH" guile
311 guile> (use-modules (gnutls))
315 <p>Alternatively, you can modify Guile’s <code>%load-path</code> variable
316 (see <a href="http://www.gnu.org/software/guile/manual/guile.html#Build-Config">Guile’s run-time options</a> in <cite>The GNU Guile
317 Reference Manual</cite>).
319 <p>At this point, you might get an error regarding
320 <samp>libguile-gnutls-v-0</samp> similar to:
322 <div class="example">
323 <pre class="example">gnutls.scm:361:1: In procedure dynamic-link in expression (load-extension "libguile-gnutls-v-0" "scm_init_gnutls"):
324 gnutls.scm:361:1: file: "libguile-gnutls-v-0", message: "libguile-gnutls-v-0.so: cannot open shared object file: No such file or directory"
327 <p>In this case, you will need to modify the run-time linker path, for
330 <div class="example">
331 <pre class="example">$ LD_LIBRARY_PATH=/usr/local/lib GUILE_LOAD_PATH=/usr/local/share/guile/site guile
332 guile> (use-modules (gnutls))
336 <p>To check that you got the intended GnuTLS library version, you may
337 print the version number of the loaded library as follows:
339 <div class="example">
340 <pre class="example">$ guile
341 guile> (use-modules (gnutls))
342 guile> (gnutls-version)

380 <h3 class="section">3.1 Enumerates and Constants</h3>
382 <a name="index-enumerate"></a>
383 <a name="index-constant"></a>
385 <p>Lots of enumerates and constants are used in the GnuTLS C API. For
386 each C enumerate type, a disjoint Scheme type is used—thus,
387 enumerate values and constants are not represented by Scheme symbols
388 nor by integers. This makes it impossible to use an enumerate value
389 of the wrong type on the Scheme side: such errors are automatically
390 detected by type-checking.
392 <p>The enumerate values are bound to variables exported by the
393 <code>(gnutls)</code> module. These variables
394 are named according to the following convention:
397 <li> All variable names are lower-case; the underscore <code>_</code>
398 character used in the C API is replaced by hyphen <code>-</code>.
399 </li><li> All variable names are prepended by the name of the enumerate
400 type and the slash <code>/</code> character.
401 </li><li> In some cases, the variable name is made more explicit than the
402 one of the C API, e.g., by avoid abbreviations.
405 <p>Consider for instance this C-side enumerate:
407 <div class="example">
408 <pre class="example">typedef enum
410 GNUTLS_CRD_CERTIFICATE = 1,
414 } gnutls_credentials_type_t;
417 <p>The corresponding Scheme values are bound to the following variables
418 exported by the <code>(gnutls)</code> module:
420 <div class="example">
421 <pre class="example">credentials/certificate
422 credentials/anonymous
427 <p>Hopefully, most variable names can be deduced from this convention.
429 <p>Scheme-side “enumerate” values can be compared using <code>eq?</code>
430 (see <a href="http://www.gnu.org/software/guile/manual/guile.html#Equality">equality predicates</a> in <cite>The GNU Guile Reference
431 Manual</cite>). Consider the following example:
433 <a name="index-session_002dcipher"></a>
435 <div class="example">
436 <pre class="example">(let ((session (make-session connection-end/client)))
442 ;; Check the ciphering algorithm currently used by SESSION.
443 (if (eq? cipher/arcfour (session-cipher session))
444 (format #t "We're using the ARCFOUR algorithm")))
447 <p>In addition, all enumerate values can be converted to a human-readable
448 string, in a type-specific way. For instance, <code>(cipher->string
449 cipher/arcfour)</code> yields <code>"ARCFOUR 128"</code>, while
450 <code>(key-usage->string key-usage/digital-signature)</code> yields
451 <code>"digital-signature"</code>. Note that these strings may not be
452 sufficient for use in a user interface since they are fairly concise
453 and not internationalized.

462 <a name="Procedure-Names-1"></a>
463 <h3 class="section">3.2 Procedure Names</h3>
465 <p>Unlike C functions in GnuTLS, the corresponding Scheme procedures are
466 named in a way that is close to natural English. Abbreviations are
467 also avoided. For instance, the Scheme procedure corresponding to
468 <code>gnutls_certificate_set_dh_params</code> is named
469 <code>set-certificate-credentials-dh-parameters!</code>. The <code>gnutls_</code>
470 prefix is always omitted from variable names since a similar effect
471 can be achieved using Guile’s nifty binding renaming facilities,
472 should it be needed (see <a href="http://www.gnu.org/software/guile/manual/guile.html#Using-Guile-Modules">Using Guile Modules</a> in <cite>The GNU
473 Guile Reference Manual</cite>).
475 <p>Often Scheme procedure names differ from C function names in a way
476 that makes it clearer what objects they operate on. For example, the
477 Scheme procedure named <code>set-session-transport-port!</code> corresponds
478 to <code>gnutls_transport_set_ptr</code>, making it clear that this
479 procedure applies to session.

487 <a name="Representation-of-Binary-Data-1"></a>
488 <h3 class="section">3.3 Representation of Binary Data</h3>
490 <p>Many procedures operate on binary data. For instance,
491 <code>pkcs3-import-dh-parameters</code> expects binary data as input and,
492 similarly, procedures like <code>pkcs1-export-rsa-parameters</code> return
495 <a name="index-SRFI_002d4"></a>
496 <a name="index-homogeneous-vector"></a>
498 <p>Binary data is represented on the Scheme side using SRFI-4 homogeneous
499 vectors (see <a href="http://www.gnu.org/software/guile/manual/guile.html#SRFI_002d4">SRFI-4</a> in <cite>The GNU Guile Reference Manual</cite>).
500 Although any type of homogeneous vector may be used, <code>u8vector</code>s
501 (i.e., vectors of bytes) are highly recommended.
503 <p>As an example, generating and then exporting RSA parameters in the PEM
504 format can be done as follows:
506 <a name="index-make_002drsa_002dparameters"></a>
507 <a name="index-pkcs1_002dexport_002drsa_002dparameters"></a>
508 <a name="index-x509_002dcertificate_002dformat_002fpem"></a>
510 <div class="example">
511 <pre class="example">(let* ((rsa-params (make-rsa-parameters 1024))
513 (pkcs1-export-rsa-parameters rsa-params
514 x509-certificate-format/pem)))
515 (uniform-vector-write raw-data (open-output-file "some-file.pem")))

533 <p>The underlying transport of a TLS session can be any Scheme
534 input/output port (see <a href="http://www.gnu.org/software/guile/manual/guile.html#Ports-and-File-Descriptors">Ports and File Descriptors</a> in <cite>The GNU
535 Guile Reference Manual</cite>). This has to be specified using
536 <code>set-session-transport-port!</code>.
538 <p>However, for better performance, a raw file descriptor can be
539 specified, using <code>set-session-transport-fd!</code>. For instance, if
540 the transport layer is a socket port over an OS-provided socket, you
541 can use the <code>port->fdes</code> or <code>fileno</code> procedure to obtain the
542 underlying file descriptor and pass it to
543 <code>set-session-transport-fd!</code> (see <a href="http://www.gnu.org/software/guile/manual/guile.html#Ports-and-File-Descriptors"><code>port->fdes</code> and <code>fileno</code></a> in <cite>The GNU Guile Reference
544 Manual</cite>). This would work as follows:
546 <div class="example">
547 <pre class="example">(let ((socket (socket PF_INET SOCK_STREAM 0))
548 (session (make-session connection-end/client)))
551 ;; Establish a TCP connection...
554 ;; Use the file descriptor that underlies SOCKET.
555 (set-session-transport-fd! session (fileno socket)))
558 <a name="index-session_002drecord_002dport"></a>
560 <p>Once a TLS session is established, data can be communicated through it
561 (i.e., <em>via</em> the TLS record layer) using the port returned by
562 <code>session-record-port</code>:
564 <div class="example">
565 <pre class="example">(let ((session (make-session connection-end/client)))
568 ;; Initialize the various parameters of SESSION, set up
569 ;; a network connection, etc...
572 (let ((i/o (session-record-port session)))
573 (write "Hello peer!" i/o)
574 (let ((greetings (read i/o)))

604 <p>GnuTLS errors are implemented as Scheme exceptions (see <a href="http://www.gnu.org/software/guile/manual/guile.html#Exceptions">exceptions in Guile</a> in <cite>The GNU Guile Reference Manual</cite>). Each
605 time a GnuTLS function returns an error, an exception with key
606 <code>gnutls-error</code> is raised. The additional arguments that are
607 thrown include an error code and the name of the GnuTLS procedure that
608 raised the exception. The error code is pretty much like an enumerate
609 value: it is one of the <code>error/</code> variables exported by the
610 <code>(gnutls)</code> module (see <a href="#Enumerates-and-Constants">Enumerates and Constants</a>). Exceptions
611 can be turned into error messages using the <code>error->string</code>
614 <p>The following examples illustrates how GnuTLS exceptions can be
617 <div class="example">
618 <pre class="example">(let ((session (make-session connection-end/server)))
627 (lambda (key err function . currently-unused)
628 (format (current-error-port)
629 "a GnuTLS error was raised by `~a': ~a~%"
630 function (error->string err)))))
633 <p>Again, error values can be compared using <code>eq?</code>:
635 <div class="example">
636 <pre class="example"> ;; `gnutls-error' handler.
637 (lambda (key err function . currently-unused)
638 (if (eq? err error/fatal-alert-received)
639 (format (current-error-port)
640 "a fatal alert was caught!~%")
641 (format (current-error-port)
642 "something bad happened: ~a~%"
643 (error->string err))))
646 <p>Note that the <code>catch</code> handler is currently passed only 3
647 arguments but future versions might provide it with additional
648 arguments. Thus, it must be prepared to handle more than 3 arguments,

766 <h3 class="section">4.2 OpenPGP Authentication Guile Example</h3>
768 <p>GnuTLS allows users to authenticate using OpenPGP certificates.
769 Using OpenPGP-based authentication is not more complicated than using
770 anonymous authentication. It requires a bit of extra work, though, to
771 import the OpenPGP public and private key of the client/server. Key
772 import is omitted here and is left as an exercise to the reader
773 (see <a href="#Importing-OpenPGP-Keys-Guile-Example">Importing OpenPGP Keys Guile Example</a>).
775 <p>Assuming <var>some-socket</var> is bound to an open socket port and
776 <var>pub</var> and <var>sec</var> are bound to the client’s OpenPGP public and
777 secret key, respectively, client-side code would look like this:
779 <a name="index-certificate_002dtype_002fopenpgp"></a>
781 <div class="example">
782 <pre class="example">;; Client-side.
784 (define %certs (list certificate-type/openpgp))
786 (let ((client (make-session connection-end/client))
787 (cred (make-certificate-credentials)))
788 (set-session-default-priority! client)
790 ;; Choose OpenPGP certificates.
791 (set-session-certificate-type-priority! client %certs)
793 ;; Prepare appropriate client credentials.
794 (set-certificate-credentials-openpgp-keys! cred pub sec)
795 (set-session-credentials! client cred)
797 ;; Specify the underlying transport socket.
798 (set-session-transport-fd! client (fileno some-socket))
801 (write "hello, world!" (session-record-port client))
802 (bye client close-request/rdwr))
805 <p>Similarly, server-side code would be along these lines:
807 <div class="example">
808 <pre class="example">;; Server-side.
810 (define %certs (list certificate-type/openpgp))
812 (let ((server (make-session connection-end/server))
813 (rsa (make-rsa-parameters 1024))
814 (dh (make-dh-parameters 1024)))
815 (set-session-default-priority! server)
817 ;; Choose OpenPGP certificates.
818 (set-session-certificate-type-priority! server %certs)
820 (let ((cred (make-certificate-credentials)))
821 ;; Prepare credentials with RSA and Diffie-Hellman parameters.
822 (set-certificate-credentials-dh-parameters! cred dh)
823 (set-certificate-credentials-rsa-export-parameters! cred rsa)
824 (set-certificate-credentials-openpgp-keys! cred pub sec)
825 (set-session-credentials! server cred))
827 (set-session-transport-fd! server (fileno some-socket))
830 (let ((msg (read (session-record-port server))))
831 (format #t "received: ~a~%" msg)
833 (bye server close-request/rdwr)))
836 <p>In practice, generating RSA parameters (and Diffie-Hellman parameters)
837 can time a long time. Thus, you may want to generate them once and
838 store them in a file for future re-use (see <a href="#Guile-Reference"><code>pkcs1-export-rsa-parameters</code> and <code>pkcs1-import-rsa-parameters</code></a>).

1600 Everyone is permitted to copy and distribute verbatim copies
1601 of this license document, but changing it is not allowed.
1607 <p>The purpose of this License is to make a manual, textbook, or other
1608 functional and useful document <em>free</em> in the sense of freedom: to
1609 assure everyone the effective freedom to copy and redistribute it,
1610 with or without modifying it, either commercially or noncommercially.
1611 Secondarily, this License preserves for the author and publisher a way
1612 to get credit for their work, while not being considered responsible
1613 for modifications made by others.
1615 <p>This License is a kind of “copyleft”, which means that derivative
1616 works of the document must themselves be free in the same sense. It
1617 complements the GNU General Public License, which is a copyleft
1618 license designed for free software.
1620 <p>We have designed this License in order to use it for manuals for free
1621 software, because free software needs free documentation: a free
1622 program should come with manuals providing the same freedoms that the
1623 software does. But this License is not limited to software manuals;
1624 it can be used for any textual work, regardless of subject matter or
1625 whether it is published as a printed book. We recommend this License
1626 principally for works whose purpose is instruction or reference.
1628 </li><li> APPLICABILITY AND DEFINITIONS
1630 <p>This License applies to any manual or other work, in any medium, that
1631 contains a notice placed by the copyright holder saying it can be
1632 distributed under the terms of this License. Such a notice grants a
1633 world-wide, royalty-free license, unlimited in duration, to use that
1634 work under the conditions stated herein. The “Document”, below,
1635 refers to any such manual or work. Any member of the public is a
1636 licensee, and is addressed as “you”. You accept the license if you
1637 copy, modify or distribute the work in a way requiring permission
1638 under copyright law.
1640 <p>A “Modified Version” of the Document means any work containing the
1641 Document or a portion of it, either copied verbatim, or with
1642 modifications and/or translated into another language.
1644 <p>A “Secondary Section” is a named appendix or a front-matter section
1645 of the Document that deals exclusively with the relationship of the
1646 publishers or authors of the Document to the Document’s overall
1647 subject (or to related matters) and contains nothing that could fall
1648 directly within that overall subject. (Thus, if the Document is in
1649 part a textbook of mathematics, a Secondary Section may not explain
1650 any mathematics.) The relationship could be a matter of historical
1651 connection with the subject or with related matters, or of legal,
1652 commercial, philosophical, ethical or political position regarding
1655 <p>The “Invariant Sections” are certain Secondary Sections whose titles
1656 are designated, as being those of Invariant Sections, in the notice
1657 that says that the Document is released under this License. If a
1658 section does not fit the above definition of Secondary then it is not
1659 allowed to be designated as Invariant. The Document may contain zero
1660 Invariant Sections. If the Document does not identify any Invariant
1661 Sections then there are none.
1663 <p>The “Cover Texts” are certain short passages of text that are listed,
1664 as Front-Cover Texts or Back-Cover Texts, in the notice that says that
1665 the Document is released under this License. A Front-Cover Text may
1666 be at most 5 words, and a Back-Cover Text may be at most 25 words.
1668 <p>A “Transparent” copy of the Document means a machine-readable copy,
1669 represented in a format whose specification is available to the
1670 general public, that is suitable for revising the document
1671 straightforwardly with generic text editors or (for images composed of
1672 pixels) generic paint programs or (for drawings) some widely available
1673 drawing editor, and that is suitable for input to text formatters or
1674 for automatic translation to a variety of formats suitable for input
1675 to text formatters. A copy made in an otherwise Transparent file
1676 format whose markup, or absence of markup, has been arranged to thwart
1677 or discourage subsequent modification by readers is not Transparent.
1678 An image format is not Transparent if used for any substantial amount
1679 of text. A copy that is not “Transparent” is called “Opaque”.
1681 <p>Examples of suitable formats for Transparent copies include plain
1682 ASCII without markup, Texinfo input format, LaTeX input
1683 format, SGML or XML using a publicly available
1684 DTD, and standard-conforming simple HTML,
1685 PostScript or PDF designed for human modification. Examples
1686 of transparent image formats include PNG, XCF and
1687 JPG. Opaque formats include proprietary formats that can be
1688 read and edited only by proprietary word processors, SGML or
1689 XML for which the DTD and/or processing tools are
1690 not generally available, and the machine-generated HTML,
1691 PostScript or PDF produced by some word processors for
1692 output purposes only.
1694 <p>The “Title Page” means, for a printed book, the title page itself,
1695 plus such following pages as are needed to hold, legibly, the material
1696 this License requires to appear in the title page. For works in
1697 formats which do not have any title page as such, “Title Page” means
1698 the text near the most prominent appearance of the work’s title,
1699 preceding the beginning of the body of the text.
1701 <p>The “publisher” means any person or entity that distributes copies
1702 of the Document to the public.
1704 <p>A section “Entitled XYZ” means a named subunit of the Document whose
1705 title either is precisely XYZ or contains XYZ in parentheses following
1706 text that translates XYZ in another language. (Here XYZ stands for a
1707 specific section name mentioned below, such as “Acknowledgements”,
1708 “Dedications”, “Endorsements”, or “History”.) To “Preserve the Title”
1709 of such a section when you modify the Document means that it remains a
1710 section “Entitled XYZ” according to this definition.
1712 <p>The Document may include Warranty Disclaimers next to the notice which
1713 states that this License applies to the Document. These Warranty
1714 Disclaimers are considered to be included by reference in this
1715 License, but only as regards disclaiming warranties: any other
1716 implication that these Warranty Disclaimers may have is void and has
1717 no effect on the meaning of this License.
1719 </li><li> VERBATIM COPYING
1721 <p>You may copy and distribute the Document in any medium, either
1722 commercially or noncommercially, provided that this License, the
1723 copyright notices, and the license notice saying this License applies
1724 to the Document are reproduced in all copies, and that you add no other
1725 conditions whatsoever to those of this License. You may not use
1726 technical measures to obstruct or control the reading or further
1727 copying of the copies you make or distribute. However, you may accept
1728 compensation in exchange for copies. If you distribute a large enough
1729 number of copies you must also follow the conditions in section 3.
1731 <p>You may also lend copies, under the same conditions stated above, and
1732 you may publicly display copies.
1734 </li><li> COPYING IN QUANTITY
1736 <p>If you publish printed copies (or copies in media that commonly have
1737 printed covers) of the Document, numbering more than 100, and the
1738 Document’s license notice requires Cover Texts, you must enclose the
1739 copies in covers that carry, clearly and legibly, all these Cover
1740 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
1741 the back cover. Both covers must also clearly and legibly identify
1742 you as the publisher of these copies. The front cover must present
1743 the full title with all words of the title equally prominent and
1744 visible. You may add other material on the covers in addition.
1745 Copying with changes limited to the covers, as long as they preserve
1746 the title of the Document and satisfy these conditions, can be treated
1747 as verbatim copying in other respects.
1749 <p>If the required texts for either cover are too voluminous to fit
1750 legibly, you should put the first ones listed (as many as fit
1751 reasonably) on the actual cover, and continue the rest onto adjacent
1754 <p>If you publish or distribute Opaque copies of the Document numbering
1755 more than 100, you must either include a machine-readable Transparent
1756 copy along with each Opaque copy, or state in or with each Opaque copy
1757 a computer-network location from which the general network-using
1758 public has access to download using public-standard network protocols
1759 a complete Transparent copy of the Document, free of added material.
1760 If you use the latter option, you must take reasonably prudent steps,
1761 when you begin distribution of Opaque copies in quantity, to ensure
1762 that this Transparent copy will remain thus accessible at the stated
1763 location until at least one year after the last time you distribute an
1764 Opaque copy (directly or through your agents or retailers) of that
1765 edition to the public.
1767 <p>It is requested, but not required, that you contact the authors of the
1768 Document well before redistributing any large number of copies, to give
1769 them a chance to provide you with an updated version of the Document.
1771 </li><li> MODIFICATIONS
1773 <p>You may copy and distribute a Modified Version of the Document under
1774 the conditions of sections 2 and 3 above, provided that you release
1775 the Modified Version under precisely this License, with the Modified
1776 Version filling the role of the Document, thus licensing distribution
1777 and modification of the Modified Version to whoever possesses a copy
1778 of it. In addition, you must do these things in the Modified Version:
1781 <li> Use in the Title Page (and on the covers, if any) a title distinct
1782 from that of the Document, and from those of previous versions
1783 (which should, if there were any, be listed in the History section
1784 of the Document). You may use the same title as a previous version
1785 if the original publisher of that version gives permission.
1787 </li><li> List on the Title Page, as authors, one or more persons or entities
1788 responsible for authorship of the modifications in the Modified
1789 Version, together with at least five of the principal authors of the
1790 Document (all of its principal authors, if it has fewer than five),
1791 unless they release you from this requirement.
1793 </li><li> State on the Title page the name of the publisher of the
1794 Modified Version, as the publisher.
1796 </li><li> Preserve all the copyright notices of the Document.
1798 </li><li> Add an appropriate copyright notice for your modifications
1799 adjacent to the other copyright notices.
1801 </li><li> Include, immediately after the copyright notices, a license notice
1802 giving the public permission to use the Modified Version under the
1803 terms of this License, in the form shown in the Addendum below.
1805 </li><li> Preserve in that license notice the full lists of Invariant Sections
1806 and required Cover Texts given in the Document’s license notice.
1808 </li><li> Include an unaltered copy of this License.
1810 </li><li> Preserve the section Entitled “History”, Preserve its Title, and add
1811 to it an item stating at least the title, year, new authors, and
1812 publisher of the Modified Version as given on the Title Page. If
1813 there is no section Entitled “History” in the Document, create one
1814 stating the title, year, authors, and publisher of the Document as
1815 given on its Title Page, then add an item describing the Modified
1816 Version as stated in the previous sentence.
1818 </li><li> Preserve the network location, if any, given in the Document for
1819 public access to a Transparent copy of the Document, and likewise
1820 the network locations given in the Document for previous versions
1821 it was based on. These may be placed in the “History” section.
1822 You may omit a network location for a work that was published at
1823 least four years before the Document itself, or if the original
1824 publisher of the version it refers to gives permission.
1826 </li><li> For any section Entitled “Acknowledgements” or “Dedications”, Preserve
1827 the Title of the section, and preserve in the section all the
1828 substance and tone of each of the contributor acknowledgements and/or
1829 dedications given therein.
1831 </li><li> Preserve all the Invariant Sections of the Document,
1832 unaltered in their text and in their titles. Section numbers
1833 or the equivalent are not considered part of the section titles.
1835 </li><li> Delete any section Entitled “Endorsements”. Such a section
1836 may not be included in the Modified Version.
1838 </li><li> Do not retitle any existing section to be Entitled “Endorsements” or
1839 to conflict in title with any Invariant Section.
1841 </li><li> Preserve any Warranty Disclaimers.
1844 <p>If the Modified Version includes new front-matter sections or
1845 appendices that qualify as Secondary Sections and contain no material
1846 copied from the Document, you may at your option designate some or all
1847 of these sections as invariant. To do this, add their titles to the
1848 list of Invariant Sections in the Modified Version’s license notice.
1849 These titles must be distinct from any other section titles.
1851 <p>You may add a section Entitled “Endorsements”, provided it contains
1852 nothing but endorsements of your Modified Version by various
1853 parties—for example, statements of peer review or that the text has
1854 been approved by an organization as the authoritative definition of a
1857 <p>You may add a passage of up to five words as a Front-Cover Text, and a
1858 passage of up to 25 words as a Back-Cover Text, to the end of the list
1859 of Cover Texts in the Modified Version. Only one passage of
1860 Front-Cover Text and one of Back-Cover Text may be added by (or
1861 through arrangements made by) any one entity. If the Document already
1862 includes a cover text for the same cover, previously added by you or
1863 by arrangement made by the same entity you are acting on behalf of,
1864 you may not add another; but you may replace the old one, on explicit
1865 permission from the previous publisher that added the old one.
1867 <p>The author(s) and publisher(s) of the Document do not by this License
1868 give permission to use their names for publicity for or to assert or
1869 imply endorsement of any Modified Version.
1871 </li><li> COMBINING DOCUMENTS
1873 <p>You may combine the Document with other documents released under this
1874 License, under the terms defined in section 4 above for modified
1875 versions, provided that you include in the combination all of the
1876 Invariant Sections of all of the original documents, unmodified, and
1877 list them all as Invariant Sections of your combined work in its
1878 license notice, and that you preserve all their Warranty Disclaimers.
1880 <p>The combined work need only contain one copy of this License, and
1881 multiple identical Invariant Sections may be replaced with a single
1882 copy. If there are multiple Invariant Sections with the same name but
1883 different contents, make the title of each such section unique by
1884 adding at the end of it, in parentheses, the name of the original
1885 author or publisher of that section if known, or else a unique number.
1886 Make the same adjustment to the section titles in the list of
1887 Invariant Sections in the license notice of the combined work.
1889 <p>In the combination, you must combine any sections Entitled “History”
1890 in the various original documents, forming one section Entitled
1891 “History”; likewise combine any sections Entitled “Acknowledgements”,
1892 and any sections Entitled “Dedications”. You must delete all
1893 sections Entitled “Endorsements.”
1895 </li><li> COLLECTIONS OF DOCUMENTS
1897 <p>You may make a collection consisting of the Document and other documents
1898 released under this License, and replace the individual copies of this
1899 License in the various documents with a single copy that is included in
1900 the collection, provided that you follow the rules of this License for
1901 verbatim copying of each of the documents in all other respects.
1903 <p>You may extract a single document from such a collection, and distribute
1904 it individually under this License, provided you insert a copy of this
1905 License into the extracted document, and follow this License in all
1906 other respects regarding verbatim copying of that document.
1908 </li><li> AGGREGATION WITH INDEPENDENT WORKS
1910 <p>A compilation of the Document or its derivatives with other separate
1911 and independent documents or works, in or on a volume of a storage or
1912 distribution medium, is called an “aggregate” if the copyright
1913 resulting from the compilation is not used to limit the legal rights
1914 of the compilation’s users beyond what the individual works permit.
1915 When the Document is included in an aggregate, this License does not
1916 apply to the other works in the aggregate which are not themselves
1917 derivative works of the Document.
1919 <p>If the Cover Text requirement of section 3 is applicable to these
1920 copies of the Document, then if the Document is less than one half of
1921 the entire aggregate, the Document’s Cover Texts may be placed on
1922 covers that bracket the Document within the aggregate, or the
1923 electronic equivalent of covers if the Document is in electronic form.
1924 Otherwise they must appear on printed covers that bracket the whole
1927 </li><li> TRANSLATION
1929 <p>Translation is considered a kind of modification, so you may
1930 distribute translations of the Document under the terms of section 4.
1931 Replacing Invariant Sections with translations requires special
1932 permission from their copyright holders, but you may include
1933 translations of some or all Invariant Sections in addition to the
1934 original versions of these Invariant Sections. You may include a
1935 translation of this License, and all the license notices in the
1936 Document, and any Warranty Disclaimers, provided that you also include
1937 the original English version of this License and the original versions
1938 of those notices and disclaimers. In case of a disagreement between
1939 the translation and the original version of this License or a notice
1940 or disclaimer, the original version will prevail.
1942 <p>If a section in the Document is Entitled “Acknowledgements”,
1943 “Dedications”, or “History”, the requirement (section 4) to Preserve
1944 its Title (section 1) will typically require changing the actual
1947 </li><li> TERMINATION
1949 <p>You may not copy, modify, sublicense, or distribute the Document
1950 except as expressly provided under this License. Any attempt
1951 otherwise to copy, modify, sublicense, or distribute it is void, and
1952 will automatically terminate your rights under this License.
1954 <p>However, if you cease all violation of this License, then your license
1955 from a particular copyright holder is reinstated (a) provisionally,
1956 unless and until the copyright holder explicitly and finally
1957 terminates your license, and (b) permanently, if the copyright holder
1958 fails to notify you of the violation by some reasonable means prior to
1959 60 days after the cessation.
1961 <p>Moreover, your license from a particular copyright holder is
1962 reinstated permanently if the copyright holder notifies you of the
1963 violation by some reasonable means, this is the first time you have
1964 received notice of violation of this License (for any work) from that
1965 copyright holder, and you cure the violation prior to 30 days after
1966 your receipt of the notice.
1968 <p>Termination of your rights under this section does not terminate the
1969 licenses of parties who have received copies or rights from you under
1970 this License. If your rights have been terminated and not permanently
1971 reinstated, receipt of a copy of some or all of the same material does
1972 not give you any rights to use it.
1974 </li><li> FUTURE REVISIONS OF THIS LICENSE
1976 <p>The Free Software Foundation may publish new, revised versions

1997 <p>“Massive Multiauthor Collaboration Site” (or “MMC Site”) means any
1998 World Wide Web server that publishes copyrightable works and also
1999 provides prominent facilities for anybody to edit those works. A
2000 public wiki that anybody can edit is an example of such a server. A
2001 “Massive Multiauthor Collaboration” (or “MMC”) contained in the
2002 site means any set of copyrightable works thus published on the MMC
2005 <p>“CC-BY-SA” means the Creative Commons Attribution-Share Alike 3.0
2006 license published by Creative Commons Corporation, a not-for-profit
2007 corporation with a principal place of business in San Francisco,
2008 California, as well as future copyleft versions of that license
2009 published by that same organization.
2011 <p>“Incorporate” means to publish or republish a Document, in whole or
2012 in part, as part of another Document.
2014 <p>An MMC is “eligible for relicensing” if it is licensed under this
2015 License, and if all works that were first published under this License
2016 somewhere other than this MMC, and subsequently incorporated in whole
2017 or in part into the MMC, (1) had no cover texts or invariant sections,
2018 and (2) were thus incorporated prior to November 1, 2008.
2020 <p>The operator of an MMC Site may republish an MMC contained in the site
2021 under CC-BY-SA on the same site at any time before August 1, 2009,
2022 provided the MMC is eligible for relicensing.
