Yamaha MMP1, Getting Started

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.

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.

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
