Indicaciones sobre nombres de marcas y sobre el uso de "Open Source Software"
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 Lessof 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 on-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.
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 meansall
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.
