If you are using a source distribution of VLC, for example a tarball or
the CVS, then you have probably used "make install" to install the
compiled VLC. To remove it just "make uninstall". If you want to
install a newer version than the currently installed one, you should
first uninstall the first one. If you deleted the original source tree,
a "make uninstall" in the newer tree should still work.

<para>The purpose of this License is to make a manual, textbook, or
other functional and useful document "free" in the sense of freedom: to
assure everyone the effective freedom to copy and redistribute it, with
or without modifying it, either commercially or noncommercially.
Secondarily, this License preserves for the author and publisher a way
to get credit for their work, while not being considered responsible for
modifications made by others.</para>
<para>This License is a kind of "copyleft", which means that derivative
works of the document must themselves be free in the same sense. It
complements the GNU General Public License, which is a copyleft license
designed for free software.</para>
<para>We have designed this License in order to use it for manuals for
free software, because free software needs free documentation: a free
program should come with manuals providing the same freedoms that the
software does. But this License is not limited to software manuals; it
can be used for any textual work, regardless of subject matter or
whether it is published as a printed book. We recommend this License
principally for works whose purpose is instruction or reference.</para>
</section>
<section id="gfdl-1"><title>APPLICABILITY AND DEFINITIONS</title>
<para id="gfdl-doc">This License applies to any manual or other work, in
any medium, that contains a notice placed by the copyright holder saying
it can be distributed under the terms of this License. Such a notice
grants a world-wide, royalty-free license, unlimited in duration, to use
that work under the conditions stated herein. The "Document", below,
refers to any such manual or work. Any member of the public is a
licensee, and is addressed as "you". You accept the license if you
copy, modify or distribute the work in a way requiring permission under
copyright law.</para>
<para id="gfdl-mod-ver">A "Modified Version" of the Document means any
work containing the Document or a portion of it, either copied verbatim,
or with modifications and/or translated into another language.</para>
<para id="gfdl-secnd-sect">A "Secondary Section" is a named appendix or
a front-matter section of the Document that deals exclusively with the
relationship of the publishers or authors of the Document to the
Document's overall subject (or to related matters) and contains nothing
that could fall directly within that overall subject. (Thus, if the
Document is in part a textbook of mathematics, a Secondary Section may
not explain any mathematics.) The relationship could be a matter of
historical connection with the subject or with related matters, or of
legal, commercial, philosophical, ethical or political position
regarding them.</para>
<para id="gfdl-inv-sect">The "Invariant Sections" are certain Secondary
Sections whose titles are designated, as being those of Invariant
Sections, in the notice that says that the Document is released under
this License. If a section does not fit the above definition of
Secondary then it is not allowed to be designated as Invariant. The
Document may contain zero Invariant Sections. If the Document does not
identify any Invariant Sections then there are none.</para>
<para id="gfdl-cov-text">The "Cover Texts" are certain short passages of
text that are listed, as Front-Cover Texts or Back-Cover Texts, in the
notice that says that the Document is released under this License. A
Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at
most 25 words.</para>
<para id="gfdl-transparent">A "Transparent" copy of the Document means a
machine-readable copy, represented in a format whose specification is
available to the general public, that is suitable for revising the
document straightforwardly with generic text editors or (for images
composed of pixels) generic paint programs or (for drawings) some widely
available drawing editor, and that is suitable for input to text
formatters or for automatic translation to a variety of formats suitable
for input to text formatters. A copy made in an otherwise Transparent
file format whose markup, or absence of markup, has been arranged to
thwart or discourage subsequent modification by readers is not
Transparent. An image format is not Transparent if used for any
substantial amount of text. A copy that is not "Transparent" is called
"Opaque".</para>
<para>Examples of suitable formats for Transparent copies include plain
ASCII without markup, Texinfo input format, LaTeX input format, SGML or
XML using a publicly available DTD, and standard-conforming simple HTML,
PostScript or PDF designed for human modification. Examples of
transparent image formats include PNG, XCF and JPG. Opaque formats
include proprietary formats that can be read and edited only by
proprietary word processors, SGML or XML for which the DTD and/or
processing tools are not generally available, and the machine-generated
HTML, PostScript or PDF produced by some word processors for output
purposes only.</para>
<para id="gfdl-title-page">The "Title Page" means, for a printed book,
the title page itself, plus such following pages as are needed to hold,
legibly, the material this License requires to appear in the title page.
For works in formats which do not have any title page as such, "Title
Page" means the text near the most prominent appearance of the work's
title, preceding the beginning of the body of the text.</para>
<para id="gfdl-entitled">A section "Entitled XYZ" means a named subunit
of the Document whose title either is precisely XYZ or contains XYZ in
parentheses following text that translates XYZ in another language.
(Here XYZ stands for a specific section name mentioned below, such as
"Acknowledgements", "Dedications", "Endorsements", or "History".) To
"Preserve the Title" of such a section when you modify the Document
means that it remains a section "Entitled XYZ" according to this
definition.</para>
<para>The Document may include Warranty Disclaimers next to the notice
which states that this License applies to the Document. These Warranty
Disclaimers are considered to be included by reference in this License,
but only as regards disclaiming warranties: any other implication that
these Warranty Disclaimers may have is void and has no effect on the
meaning of this License.</para>

<section id="gfdl-2"><title>VERBATIM COPYING</title>
<para>You may copy and distribute the Document in any medium, either
commercially or noncommercially, provided that this License, the
copyright notices, and the license notice saying this License applies to
the Document are reproduced in all copies, and that you add no other
conditions whatsoever to those of this License. You may not use
technical measures to obstruct or control the reading or further copying
of the copies you make or distribute. However, you may accept
compensation in exchange for copies. If you distribute a large enough
number of copies you must also follow the conditions in section 3.
</para>
<para>You may also lend copies, under the same conditions stated above,
and you may publicly display copies.</para>
</section>
<section id="gfdl-3"><title>COPYING IN QUANTITY</title>
<para>If you publish printed copies (or copies in media that commonly
have printed covers) of the Document, numbering more than 100, and the
Document's license notice requires Cover Texts, you must enclose the
copies in covers that carry, clearly and legibly, all these Cover Texts:
Front-Cover Texts on the front cover, and Back-Cover Texts on the back
cover. Both covers must also clearly and legibly identify you as the
publisher of these copies. The front cover must present the full title
with all words of the title equally prominent and visible. You may add
other material on the covers in addition. Copying with changes limited
to the covers, as long as they preserve the title of the Document and
satisfy these conditions, can be treated as verbatim copying in other
respects.</para>
<para>If the required texts for either cover are too voluminous to fit
legibly, you should put the first ones listed (as many as fit
reasonably) on the actual cover, and continue the rest onto adjacent
pages.</para>
<para>If you publish or distribute Opaque copies of the Document
numbering more than 100, you must either include a machine-readable
Transparent copy along with each Opaque copy, or state in or with each
Opaque copy a computer-network location from which the general
network-using public has access to download using public-standard
network protocols a complete Transparent copy of the Document, free of
added material. If you use the latter option, you must take reasonably
prudent steps, when you begin distribution of Opaque copies in quantity,
to ensure that this Transparent copy will remain thus accessible at the
stated location until at least one year after the last time you
distribute an Opaque copy (directly or through your agents or retailers)
of that edition to the public.</para>

arrangements made by) any one entity. If the Document already includes
a cover text for the same cover, previously added by you or by
arrangement made by the same entity you are acting on behalf of, you may
not add another; but you may replace the old one, on explicit permission
from the previous publisher that added the old one.</para>
<para>The author(s) and publisher(s) of the Document do not by this
License give permission to use their names for publicity for or to
assert or imply endorsement of any Modified Version.</para>

<section id="gfdl-5"><title>COMBINING DOCUMENTS</title>
<para>You may combine the Document with other documents released under
this License, under the terms defined in <link linkend="gfdl-4">section
4</link> above for modified versions, provided that you include in the
combination all of the Invariant Sections of all of the original
documents, unmodified, and list them all as Invariant Sections of your
combined work in its license notice, and that you preserve all their
Warranty Disclaimers.</para>
<para>The combined work need only contain one copy of this License, and
multiple identical Invariant Sections may be replaced with a single
copy. If there are multiple Invariant Sections with the same name but
different contents, make the title of each such section unique by adding
at the end of it, in parentheses, the name of the original author or
publisher of that section if known, or else a unique number. Make the
same adjustment to the section titles in the list of Invariant Sections
in the license notice of the combined work.</para>
<para>In the combination, you must combine any sections Entitled
"History" in the various original documents, forming one section
Entitled "History"; likewise combine any sections Entitled
"Acknowledgements", and any sections Entitled "Dedications". You must
delete all sections Entitled "Endorsements".</para>

<section id="gfdl-6"><title>COLLECTIONS OF DOCUMENTS</title>
<para>You may make a collection consisting of the Document and other
documents released under this License, and replace the individual copies
of this License in the various documents with a single copy that is
included in the collection, provided that you follow the rules of this
License for verbatim copying of each of the documents in all other
respects.</para>
<para>You may extract a single document from such a collection, and
distribute it individually under this License, provided you insert a
copy of this License into the extracted document, and follow this
License in all other respects regarding verbatim copying of that
document.</para>

<section id="gfdl-7"><title>AGGREGATION WITH INDEPENDENT WORKS</title>
<para>A compilation of the Document or its derivatives with other
separate and independent documents or works, in or on a volume of a
storage or distribution medium, is called an "aggregate" if the
copyright resulting from the compilation is not used to limit the legal
rights of the compilation's users beyond what the individual works
permit. When the Document is included an aggregate, this License does
not apply to the other works in the aggregate which are not themselves
derivative works of the Document.</para>
<para>If the Cover Text requirement of section 3 is applicable to these
copies of the Document, then if the Document is less than one half of
the entire aggregate, the Document's Cover Texts may be placed on covers
