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

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.

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
