+To install Connex, the NEX:// protocol browser
+
+* download and set up cpanm, which will help you pull in required libraries:
+  * curl http://cpanmin.us | perl - -l ~/perl5 App::cpanminus local::lib
+  * eval `perl -I ~/perl5/lib/perl5 -Mlocal::lib`
+  * echo 'eval `perl -I ~/perl5/lib/perl5 -Mlocal::lib`' >> ~/.profile
+  * echo 'export MANPATH=$HOME/perl5/man:$MANPATH' >> ~/.profile
+
+
+* Unzip the package, enter:
+  * tar xvzf App-Connex-0.9.tar.gz
+
+* After you have unzipped the package, cd to the package folder App-Connex*, then enter the following commands:
+* perl Build.PL
+* ./Build
+* ./Build test
+* ./Build install
+
+Now run this command to download Perl libraries that the app needs:
+ ~/perl5/bin/cpanm --installdeps . 
+
+Now you can run with "perl script/connex.pl"

+
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The license agreements of most software companies try to keep users
+at the mercy of those companies.  By contrast, our 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.  The
+General Public License applies to the Free Software Foundation's
+software and to any other program whose authors commit to using it.
+You can use it for your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Specifically, the General Public License is designed to make
+sure that you have the freedom to give away or sell copies of free
+software, 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 a 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 tell them 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.
+
+  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 Agreement 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 work containing the
+Program or a portion of it, either verbatim or with modifications.  Each
+licensee is addressed as "you".
+
+  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
+General Public License and to the absence of any warranty; and give any
+other recipients of the Program a copy of this General Public License
+along with the Program.  You may charge a fee for the physical act of
+transferring a copy.
+
+  2. You may modify your copy or copies of the Program or any portion of
+it, and copy and distribute such modifications under the terms of Paragraph
+1 above, provided that you also do the following:
+
+    a) cause the modified files to carry prominent notices stating that
+    you changed the files and the date of any change; and
+
+    b) cause the whole of any work that you distribute or publish, that
+    in whole or in part contains the Program or any part thereof, either
+    with or without modifications, to be licensed at no charge to all
+    third parties under the terms of this General Public License (except
+    that you may choose to grant warranty protection to some or all
+    third parties, at your option).
+
+    c) If the modified program normally reads commands interactively when
+    run, you must cause it, when started running for such interactive use
+    in the simplest and most usual 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 General
+    Public License.
+
+    d) 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.
+
+Mere aggregation of another independent work with the Program (or its
+derivative) on a volume of a storage or distribution medium does not bring
+the other work under the scope of these terms.
+
+  3. You may copy and distribute the Program (or a portion or derivative of
+it, under Paragraph 2) in object code or executable form under the terms of
+Paragraphs 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
+    Paragraphs 1 and 2 above; or,
+
+    b) accompany it with a written offer, valid for at least three
+    years, to give any third party free (except for a nominal charge
+    for the cost of distribution) a complete machine-readable copy of the
+    corresponding source code, to be distributed under the terms of
+    Paragraphs 1 and 2 above; or,
+
+    c) accompany it with the information you received as to where the
+    corresponding source code may be obtained.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form alone.)
+
+Source code for a work means the preferred form of the work for making
+modifications to it.  For an executable file, complete source code means
+all the source code for all modules it contains; but, as a special
+exception, it need not include source code for modules which are standard
+libraries that accompany the operating system on which the executable
+file runs, or for standard header files or definitions files that
+accompany that operating system.
+
+  4. You may not copy, modify, sublicense, distribute or transfer the
+Program except as expressly provided under this General Public License.
+Any attempt otherwise to copy, modify, sublicense, distribute or transfer
+the Program is void, and will automatically terminate your rights to use
+the Program under this License.  However, parties who have received
+copies, or rights to use copies, from you under this General Public
+License will not have their licenses terminated so long as such parties
+remain in full compliance.
+
+  5. By copying, distributing or modifying 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.
+
+  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.
+
+  7. 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 the 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
+the license, you may choose any version ever published by the Free Software
+Foundation.
+
+  8. 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
+
+  9. 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.
+
+  10. 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.
+
+                     END OF TERMS AND CONDITIONS
+
+        Appendix: 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 humanity, 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>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 1, or (at your option)
+    any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston MA  02110-1301 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19xx name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the
+appropriate parts of the General Public License.  Of course, the
+commands you use may be called something other than `show w' and `show
+c'; they could even be mouse-clicks or menu items--whatever suits your
+program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  program `Gnomovision' (a program to direct compilers to make passes
+  at assemblers) written by James Hacker.

+
+  The Perl Artistic License 1.0
+
+
+
+
+
+                         The "Artistic License"
+
+                                Preamble
+
+The intent of this document is to state the conditions under which a
+Package may be copied, such that the Copyright Holder maintains some
+semblance of artistic control over the development of the package,
+while giving the users of the package the right to use and distribute
+the Package in a more-or-less customary fashion, plus the right to make
+reasonable modifications.
+
+Definitions:
+
+        "Package" refers to the collection of files distributed by the
+        Copyright Holder, and derivatives of that collection of files
+        created through textual modification.
+
+        "Standard Version" refers to such a Package if it has not been
+        modified, or has been modified in accordance with the wishes
+        of the Copyright Holder as specified below.
+
+        "Copyright Holder" is whoever is named in the copyright or
+        copyrights for the package.
+
+        "You" is you, if you're thinking about copying or distributing
+        this Package.
+
+        "Reasonable copying fee" is whatever you can justify on the
+        basis of media cost, duplication charges, time of people involved,
+        and so on.  (You will not be required to justify it to the
+        Copyright Holder, but only to the computing community at large
+        as a market that must bear the fee.)
+
+        "Freely Available" means that no fee is charged for the item
+        itself, though there may be fees involved in handling the item.
+        It also means that recipients of the item may redistribute it
+        under the same conditions they received it.
+
+1. You may make and give away verbatim copies of the source form of the
+Standard Version of this Package without restriction, provided that you
+duplicate all of the original copyright notices and associated disclaimers.
+
+2. You may apply bug fixes, portability fixes and other modifications
+derived from the Public Domain or from the Copyright Holder.  A Package
+modified in such a way shall still be considered the Standard Version.
+
+3. You may otherwise modify your copy of this Package in any way, provided
+that you insert a prominent notice in each changed file stating how and
+when you changed that file, and provided that you do at least ONE of the
+following:
+
+    a) place your modifications in the Public Domain or otherwise make them
+    Freely Available, such as by posting said modifications to Usenet or
+    an equivalent medium, or placing the modifications on a major archive
+    site such as uunet.uu.net, or by allowing the Copyright Holder to include
+    your modifications in the Standard Version of the Package.
+
+    b) use the modified Package only within your corporation or organization.
+
+    c) rename any non-standard executables so the names do not conflict
+    with standard executables, which must also be provided, and provide
+    a separate manual page for each non-standard executable that clearly
+    documents how it differs from the Standard Version.
+
+    d) make other distribution arrangements with the Copyright Holder.
+
+4. You may distribute the programs of this Package in object code or
+executable form, provided that you do at least ONE of the following:
+
+    a) distribute a Standard Version of the executables and library files,
+    together with instructions (in the manual page or equivalent) on where
+    to get the Standard Version.
+
+    b) accompany the distribution with the machine-readable source of
+    the Package with your modifications.
+
+    c) give non-standard executables non-standard names, and clearly
+    document the differences in manual pages (or equivalent), together
+    with instructions on where to get the Standard Version.
+
+    d) make other distribution arrangements with the Copyright Holder.
+
+5. You may charge a reasonable copying fee for any distribution of this
+Package.  You may charge any fee you choose for support of this
+Package.  You may not charge a fee for this Package itself.  However,
+you may distribute this Package in aggregate with other (possibly
+commercial) programs as part of a larger (possibly commercial) software
+distribution provided that you do not advertise this Package as a
+product of your own.  You may embed this Package's interpreter within
+an executable of yours (by linking); this shall be construed as a mere
+form of aggregation, provided that the complete Standard Version of the
+interpreter is so embedded.
+
+6. The scripts and library files supplied as input to or produced as
+output from the programs of this Package do not automatically fall
+under the copyright of this Package, but belong to whoever generated
+them, and may be sold commercially, and may be aggregated with this
+Package.  If such scripts or library files are aggregated with this
+Package via the so-called "undump" or "unexec" methods of producing a
+binary executable image, then distribution of such an image shall
+neither be construed as a distribution of this Package nor shall it
+fall under the restrictions of Paragraphs 3 and 4, provided that you do
+not represent such an executable image as a Standard Version of this
+Package.
+
+7. C subroutines (or comparably compiled subroutines in other
+languages) supplied by you and linked into this Package in order to
+emulate subroutines and variables of the language defined by this
+Package shall not be considered part of this Package, but are the
+equivalent of input as in Paragraph 6, provided these subroutines do
+not change the language in any way that would cause it to fail the
+regression tests for the language.
+
+8. Aggregation of this Package with a commercial distribution is always
+permitted provided that the use of this Package is embedded; that is,
+when no overt attempt is made to make this Package's interfaces visible
+to the end user of the commercial distribution.  Such use shall not be
+construed as a distribution of this Package.
+
+9. The name of the Copyright Holder may not be used to endorse or promote
+products derived from this software without specific prior written permission.
+
+10. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
+IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
+WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
+
+                                The End
