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 por-

tion 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 properly with a modified

version of the library, if the user installs one, as long as the

modified version is interface-compatible with the version

that the work was made with. c) Accompany the work with a

written offer, valid for at least three years, to give the same

user the materials specified in Subsection 6a, above, for a

charge no more than the cost of performing this distribution.

d) If distribution of the work is made by offering access to

copy from a designated place, offer equivalent access to copy

the above specified materials from the same place.

e) Verify that the user has already received a copy of these

materials or that you have already sent this user a copy. For

an executable, the required form of the "work that uses the

Library" must include any data and utility programs needed

for reproducing the executable from it. However, as a special

exception, the materials to be distributed need not include

anything that is normally distributed (in either source or
