+Preamble to the Gnu Lesser General Public License
+-------------------------------------------------
+Copyright (c) 2000 Franz Incorporated, Berkeley, CA 94704
+
+The concept of the GNU Lesser General Public License version 2.1
+("LGPL") has been adopted to govern the use and distribution of
+above-mentioned application. However, the LGPL uses terminology that
+is more appropriate for a program written in C than one written in
+Lisp. Nevertheless, the LGPL can still be applied to a Lisp program if
+certain clarifications are made. This document details those
+clarifications. Accordingly, the license for the open-source Lisp
+applications consists of this document plus the LGPL. Wherever there
+is a conflict between this document and the LGPL, this document takes
+precedence over the LGPL.
+
+A "Library" in Lisp is a collection of Lisp functions, data and
+foreign modules. The form of the Library can be Lisp source code (for
+processing by an interpreter) or object code (usually the result of
+compilation of source code or built with some other
+mechanisms). Foreign modules are object code in a form that can be
+linked into a Lisp executable. When we speak of functions we do so in
+the most general way to include, in addition, methods and unnamed
+functions. Lisp "data" is also a general term that includes the data
+structures resulting from defining Lisp classes. A Lisp application
+may include the same set of Lisp objects as does a Library, but this
+does not mean that the application is necessarily a "work based on the
+Library" it contains.
+
+The Library consists of everything in the distribution file set before
+any modifications are made to the files. If any of the functions or
+classes in the Library are redefined in other files, then those
+redefinitions ARE considered a work based on the Library. If
+additional methods are added to generic functions in the Library,
+those additional methods are NOT considered a work based on the
+Library. If Library classes are subclassed, these subclasses are NOT
+considered a work based on the Library. If the Library is modified to
+explicitly call other functions that are neither part of Lisp itself
+nor an available add-on module to Lisp, then the functions called by
+the modified Library ARE considered a work based on the Library. The
+goal is to ensure that the Library will compile and run without
+getting undefined function errors.
+
+It is permitted to add proprietary source code to the Library, but it
+must be done in a way such that the Library will still run without
+that proprietary code present. Section 5 of the LGPL distinguishes
+between the case of a library being dynamically linked at runtime and
+one being statically linked at build time. Section 5 of the LGPL
+states that the former results in an executable that is a "work that
+uses the Library." Section 5 of the LGPL states that the latter
+results in one that is a "derivative of the Library", which is
+therefore covered by the LGPL. Since Lisp only offers one choice,
+which is to link the Library into an executable at build time, we
+declare that, for the purpose applying the LGPL to the Library, an
+executable that results from linking a "work that uses the Library"
+with the Library is considered a "work that uses the Library" and is
+therefore NOT covered by the LGPL.
+
+Because of this declaration, section 6 of LGPL is not applicable to
+the Library. However, in connection with each distribution of this
+executable, you must also deliver, in accordance with the terms and
+conditions of the LGPL, the source code of Library (or your derivative
+thereof) that is incorporated into this executable.

+                  GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 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.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations
+below.
+
+  When we speak of free software, we are referring to freedom of use,
+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 and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+^L
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it
+becomes a de-facto standard.  To achieve this, non-free programs must
+be allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+^L
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, 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 library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete 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 distribute a copy of this License along with the
+Library.
+
+  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 Library or any portion
+of it, thus forming a work based on the Library, 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) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+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 Library, 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 Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+^L
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you 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.
+
+  If distribution of 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 satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+^L
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at least
+    three years, to give the same user the materials specified in
+    Subsection 6a, above, for a charge no more than the cost of
+    performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be 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.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+^L
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library 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.
+
+  9. 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 Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+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 with
+this License.
+^L
+  11. 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 Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library 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 Library.
+
+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.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library 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.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser 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 Library
+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 Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+^L
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+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
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.

+PURI - Portable URI Library
+===========================
+
+AUTHORS

+Kevin Rosenberg kevin@rosenberg.net

+
+DOWNLOAD
+--------
+Puri home: http://files.b9.com/puri/
+Portable tester home: http://files.b9.com/tester/
+
+
+SUPPORTED PLATFORMS
+-------------------
+   AllegroCL, CLISP, CMUCL, Lispworks, OpenMCL, SBCL
+
+
+OVERVIEW
+--------
+This is portable Universal Resource Identifier library for Common Lisp
+programs. It parses URI according to the RFC 2396 specification. It's
+is based on Franz, Inc's opensource URI package and has been ported to
+work other CL implementations. It is licensed under the LLGPL which
+is included in this distribution.
+
+A regression suite is included which uses Franz's open-source tester
+library. I've ported that library for use on other CL
+implementations. Puri completes 126/126 regression tests successfully.
+
+Franz's unmodified documentation file is included in the file
+uri.html. 
+
+
+DIFFERENCES BETWEEN PURI and NET.URI
+------------------------------------
+
+* Puri uses the package 'puri while NET.URI uses the package 'net.uri
+
+* To signal an error parsing a URI, Puri uses the condition
+  :uri-parse-error while NET.URI uses the condition :parse-error. This
+  divergence occurs because Franz's parse-error condition uses
+  :format-control and :format-arguments slots which are not in the ANSI
+  specification for the parse-error condition.

+
+<h2><a name="uri-intro-1">1.0 Introduction</a></h2>
+
+<p><em>URI</em> stands for <em>Universal Resource Identifier</em>. For a description of
+URIs, see RFC2396, which can be found in several places, including the IETF web site (<a
+href="http://www.ietf.org/rfc/rfc2396.txt%22%3Ehttp://www.ietf.org/rfc/rfc2396.txt</a>) and
+the UCI/ICS web site (<a href="http://www.ics.uci.edu/pub/ietf/uri/rfc2396.txt">http://www.ics.uci.edu/pub/ietf/uri/rfc2396.txt</a>).
+We prefer the UCI/ICS one as it has more examples. </p>
+
+<p>URIs are a superset in functionality and syntax to URLs (Universal Resource Locators)
+and URNs (Universal Resource Names). That is, RFC2396 updates and merges RFC1738 and
+RFC1808 into a single syntax, called the URI. It does exclude some portions of RFC1738
+that define specific syntax of individual URL schemes. </p>
+
+<p>In URL slang, the <em>scheme</em> is usually called the `protocol', but it is called
+scheme in RFC1738. A URL `host' corresponds to the URI `authority.' The URL slang
+`bookmark' or `anchor' is `fragment' in URI lingo. </p>
+
+<p>The URI facility was available as a patch to Allegro CL 5.0.1 and is included with
+release 6.0. the URI facility might not be in an Allegro CL image. Evaluate <code>(require
+:uri)</code> to ensure the facility is loaded (that form returns <code>nil</code> if the
+URI module is already loaded). </p>
+
+<p>Broadly, the URI facility creates a Lisp object that represents a URI, and provides
+setters and accessors to fields in the URI object. The URI object can also be interned,
+much like symbols in CL are. This document describes the facility and the related
+operators. </p>
+
+<p>Aside from the obvious slots which are called out in the RFC, URIs also have a property
+list. With interning, this is another similarity between URIs and CL symbols. </p>
+
+<hr>
+
+<hr>
+
+<h2><a name="uri-api-1">2.0 The URI API definition</a></h2>
+
+<p>Symbols naming objects (functions, variables, etc.) in the <em>uri</em> module are
+exported from the <code>net.uri</code> package. </p>
+
+<p>URIs are represented by CLOS objects. Their slots are: </p>
+
+<pre>
+scheme 
+host 
+port 
+path 
+query
+fragment 
+plist 
+</pre>
+
+<p>The <code>host</code> and <code>port</code> slots together correspond to the <code>authority</code>
+(see RFC2396). There is an accessor-like function, <a href="operators/uri-authority.htm"><b>uri-authority</b></a>,
+that can be used to extract the authority from a URI. See the RFC2396 specifications
+pointed to at the beginning of the <a href="#uri-intro-1">1.0 Introduction</a> for details
+of all the slots except <code>plist</code>. The <code>plist</code> slot contains a
+standard Common Lisp property list. </p>
+
+<p>All symbols are external in the <code>net.uri</code> package, unless otherwise noted.
+Brief descriptions are given in this document, with complete descriptions in the
+individual pages.

+<h2><a name="parsing-decoding-1">3.0 Parsing, escape decoding/encoding and the path</a></h2>
+
+<p>The method <a href="operators/uri-path.htm"><b>uri-path</b></a> returns the path
+portion of the URI, in string form. The method <a href="operators/uri-parsed-path.htm"><b>uri-parsed-path</b></a>
+returns the path portion of the URI, in list form. This list form is discussed below,
+after a discussion of decoding/encoding. </p>
+
+<p>RFC2396 lays out a method for inserting into URIs <em>reserved characters</em>. You do
+this by escaping the character. An <em>escaped</em> character is defined like this: </p>
+
+<pre>
+escaped = &quot;%&quot; hex hex 
+
+hex = digit | &quot;A&quot; | &quot;B&quot; | &quot;C&quot; | &quot;D&quot; | &quot;E&quot; | &quot;F&quot; | &quot;a&quot; | &quot;b&quot; | &quot;c&quot; | &quot;d&quot; | &quot;e&quot; | &quot;f&quot; 
+</pre>
+
+<p>In addition, the RFC defines excluded characters: </p>
+
+<pre>
+&quot;&lt;&quot; | &quot;&gt;&quot; | &quot;#&quot; | &quot;%&quot; | &lt;&quot;&gt; | &quot;{&quot; | &quot;}&quot; | &quot;|&quot; | &quot;&quot; | &quot;^&quot; | &quot;[&quot; | &quot;]&quot; | &quot;`&quot; 
+</pre>
+
+<p>The set of reserved characters are: </p>
+
+<pre>
+&quot;;&quot; | &quot;/&quot; | &quot;?&quot; | &quot;:&quot; | &quot;@&quot; | &quot;&amp;&quot; | &quot;=&quot; | &quot;+&quot; | &quot;$&quot; | &quot;,&quot; 
+</pre>
+
+<p>with the following exceptions: 
+
+<ul>
+  <li>within the authority component, the characters &quot;;&quot;, &quot;:&quot;,
+    &quot;@&quot;, &quot;?&quot;, and &quot;/&quot; are reserved. </li>
+  <li>within a path segment, the characters &quot;/&quot;, &quot;;&quot;, &quot;=&quot;, and
+    &quot;?&quot; are reserved. </li>
+  <li>within a query component, the characters &quot;;&quot;, &quot;/&quot;, &quot;?&quot;,
+    &quot;:&quot;, &quot;@&quot;, &quot;&amp;&quot;, &quot;=&quot;, &quot;+&quot;,
+    &quot;,&quot;, and &quot;$&quot; are reserved. </li>
+</ul>
+
+<p>From the RFC, there are two important rules about escaping and unescaping (encoding and
+decoding): 
+
+<ul>
+  <li>decoding should only happen when the URI is parsed into component parts;</li>
+  <li>encoding can only occur when a URI is made from component parts (ie, rendered for
+    printing). </li>
+</ul>
+
+<p>The implication of this is that to decode the URI, it must be in a parsed state. That
+is, you can't convert <font face="Courier New">%2f</font> (the escaped form of
+&quot;/&quot;) until the path has been parsed into its component parts. Another important
+desire is for the application viewing the component parts to see the decoded values of the
+components. For example, consider: </p>
+
+<pre>
+http://www.franz.com/calculator/3%2f2 
+</pre>
+
+<p>This might be the implementation of a calculator, and how someone would execute 3/2.
+Clearly, the application that implements this would want to see path components of
+&quot;calculator&quot; and &quot;3/2&quot;. &quot;3%2f2&quot; would not be useful to the
+calculator application. </p>
+
+<p>For the reasons given above, a parsed version of the path is available and has the
+following form: </p>
+
+<pre>
+([:absolute | :relative] component1 [component2...]) 
+</pre>
+
+<p>where components are: </p>
+
+<pre>
+element | (element param1 [param2 ...]) 
+</pre>
+
+<p>and <em>element</em> is a path element, and the param's are path element parameters.
+For example, the result of </p>
+
+<pre>
+(uri-parsed-path (parse-uri &quot;foo;10/bar:x;y;z/baz.htm&quot;)) 
+</pre>
+
+<p>is </p>
+
+<pre>
+(:relative (&quot;foo&quot; &quot;10&quot;) (&quot;bar:x&quot; &quot;y&quot; &quot;z&quot;) &quot;baz.htm&quot;) 
+</pre>
+
+<p>There is a certain amount of canonicalization that occurs when parsing: 
+
+<ul>
+  <li>A path of <code>(:absolute)</code> or <code>(:absolute &quot;&quot;)</code> is
+    equivalent to a <code>nil</code> path. That is, <code>http://a/</code> is parsed with a <code>nil</code>
+    path and printed as <code>http://a</code>. </li>
+  <li>Escaped characters that are not reserved are not escaped upon printing. For example, <code>&quot;foob%61r&quot;</code>
+    is parsed into <code>&quot;foobar&quot;</code> and appears as <code>&quot;foobar&quot;</code>
+    when the URI is printed. </li>
+</ul>

+<h2><a name="interning-uris-1">4.0 Interning URIs</a></h2>
+
+<p>This section describes how to intern URIs. Interning is not mandatory. URIs can be used
+perfectly well without interning them. </p>
+
+<p>Interned URIs in Allegro are like symbols. That is, a string representing a URI, when
+parsed and interned, will always yield an <strong>eq</strong> object. For example: </p>
+
+<pre>
+(eq (intern-uri &quot;http://www.franz.com%22;) 
+    (intern-uri &quot;http://www.franz.com%22;)) 
+</pre>
+
+<p>is always true. (Two strings with identical contents may or may not be <strong>eq</strong>
+in Common Lisp, note.) </p>
+
+<p>The functions associated with interning are: 
+
+<ul>
+  <li><a href="operators/make-uri-space.htm"><b>make-uri-space</b></a> <p><b>Arguments: </b>&amp;key
+    <i>size </i></p>
+    <p>Make a new hash-table object to contain interned URIs. </p>
+  </li>

+  </li>
+  <li><a href="operators/uri_eq.htm"><b>uri=</b></a> <p><b>Arguments: </b><i>uri1 uri2 </i></p>
+    <p>Returns true if <i>uri1</i> and <i>uri2</i> are equivalent. </p>
+  </li>
+  <li><a href="operators/intern-uri.htm"><b>intern-uri</b></a> <p><b>Arguments: </b><i>uri-name
+    </i>&amp;optional <i>uri-space </i></p>

+<ol>
+  <li>The following are true: <br>
+    <code>(uri= (parse-uri &quot;http://www.franz.com/%22;)</code> <br>
+    &nbsp; &nbsp; <code>(parse-uri &quot;http://www.franz.com%22;))</code> <br>
+    <code>(eq (intern-uri &quot;http://www.franz.com/%22;)</code> <br>
+    &nbsp;&nbsp; <code>(intern-uri &quot;http://www.franz.com%22;))</code><br>
+  </li>
+  <li>The following is true: <br>
+    <code>(eq (intern-uri &quot;http://www.franz.com:80/foo/bar.htm%22;)</code> <br>
+    &nbsp; &nbsp; <code>(intern-uri &quot;http://www.franz.com/foo/bar.htm%22;))</code><br>
+    (I.e. specifying the default port is the same as specifying no port at all. This is
+    specific in RFC2396.) </li>
+  <li>The <em>scheme</em> and <em>authority</em> are case-insensitive. In Allegro CL, the
+    scheme is a keyword that appears in the normal case for the Lisp in which you are
+    executing. </li>
+  <li><code>#u&quot;...&quot;</code> is shorthand for <code>(parse-uri &quot;...&quot;)</code>
+    but if an existing <code>#u</code> dispatch macro definition exists, it will not be
+    overridden. </li>
+  <li>The interaction between setting the scheme, host, port, path, query, and fragment slots
+    of URI objects, in conjunction with interning URIs will have very bad and unpredictable
+    results. </li>
+  <li>The printable representation of URIs is cached, for efficiency. This caching is undone
+    when the above slots are changed. That is, when you create a URI the printed
+    representation is cached. When you change one of the above mentioned slots, the printed
+    representation is cleared and calculated when the URI is next printed. For example: </li>
+</ol>
+
+<pre>
+user(10): (setq u #u&quot;http://foo.bar.com/foo/bar%22;) 
+#&lt;uri http://foo.bar.com/foo/bar%3E; 
+user(11): (setf (net.uri:uri-host u) &quot;foo.com&quot;) 
+&quot;foo.com&quot; 
+user(12): u 
+#&lt;uri http://foo.com/foo/bar%3E; 
+user(13): 
+</pre>
+
+<p>This allows URIs behavior to follow the principle of least surprise. </p>

+trivial-gray-streams
+====================
+
+This system provides an extremely thin compatibility layer for gray
+streams.  It is nearly *too* trivial for a complete package, except that
+I have copy&pasted this code into enough projects now that I decided to
+factor it out once again now, and then *never* have to touch it again.
+
+
+How to use it
+=============
+
+1. Use the package TRIVIAL-GRAY-STREAMS instead of whatever
+   implementation-specific package you would have to use otherwise to
+   get at gray stream symbols.
+2. For STREAM-READ-SEQUENCE and STREAM-WRITE-SEQUENCE, notice that we
+   use two required arguments and allow additional keyword arguments.
+   So the lambda list when defining a method on either function should look
+   like this:
+     (stream sequence start end &key)
+3. In order for (2) to work on all Lisps, make sure to subclass all your
+   stream classes from TRIVIAL-GRAY-STREAM-MIXIN if you intend to define
+   methods on those two generic functions.
+
+
+Extensions
+==========
+
+Generic function STREAM-READ-SEQUENCE (stream sequence start end &key)
+Generic function STREAM-WRITE-SEQUENCE (stream sequence start end &key)
+
+	See above.
+
+Generic function STREAM-FILE-POSITION (stream) => file position
+Generic function (SETF STREAM-FILE-POSITION) (position-spec stream) => successp
+
+	Will only be called by LispWorks and CLISP.
