 Everyone is permitted to copy and distribute verbatim copies

 of this license document, but changing it is not allowed.

[This is the first released version of the Lesser GPL.  It also counts
10
 as the successor of the GNU Library Public License, version 2, hence
11
 the version number 2.1.]
12

  
13
			    Preamble
14

  
15
  The licenses for most software are designed to take away your
16
freedom to share and change it.  By contrast, the GNU General Public
17
Licenses are intended to guarantee your freedom to share and change
18
free software--to make sure the software is free for all its users.
19

  
20
  This license, the Lesser General Public License, applies to some
21
specially designated software packages--typically libraries--of the
22
Free Software Foundation and other authors who decide to use it.  You
23
can use it too, but we suggest you first think carefully about whether
24
this license or the ordinary General Public License is the better
25
strategy to use in any particular case, based on the explanations below.
26

  
27
  When we speak of free software, we are referring to freedom of use,
28
not price.  Our General Public Licenses are designed to make sure that
29
you have the freedom to distribute copies of free software (and charge
30
for this service if you wish); that you receive source code or can get
31
it if you want it; that you can change the software and use pieces of
32
it in new free programs; and that you are informed that you can do
33
these things.
34

  
35
  To protect your rights, we need to make restrictions that forbid
36
distributors to deny you these rights or to ask you to surrender these
37
rights.  These restrictions translate to certain responsibilities for
38
you if you distribute copies of the library or if you modify it.
39

  
40
  For example, if you distribute copies of the library, whether gratis
41
or for a fee, you must give the recipients all the rights that we gave
42
you.  You must make sure that they, too, receive or can get the source
43
code.  If you link other code with the library, you must provide
44
complete object files to the recipients, so that they can relink them
45
with the library after making changes to the library and recompiling
46
it.  And you must show them these terms so they know their rights.
47

  
48
  We protect your rights with a two-step method: (1) we copyright the
49
library, and (2) we offer you this license, which gives you legal
50
permission to copy, distribute and/or modify the library.
51

  
52
  To protect each distributor, we want to make it very clear that
53
there is no warranty for the free library.  Also, if the library is
54
modified by someone else and passed on, the recipients should know
55
that what they have is not the original version, so that the original
56
author's reputation will not be affected by problems that might be
57
introduced by others.
58

59
  Finally, software patents pose a constant threat to the existence of
60
any free program.  We wish to make sure that a company cannot
61
effectively restrict the users of a free program by obtaining a
62
restrictive license from a patent holder.  Therefore, we insist that
63
any patent license obtained for a version of the library must be
64
consistent with the full freedom of use specified in this license.
65

  
66
  Most GNU software, including some libraries, is covered by the
67
ordinary GNU General Public License.  This license, the GNU Lesser
68
General Public License, applies to certain designated libraries, and
69
is quite different from the ordinary General Public License.  We use
70
this license for certain libraries in order to permit linking those
71
libraries into non-free programs.
72

  
73
  When a program is linked with a library, whether statically or using
74
a shared library, the combination of the two is legally speaking a
75
combined work, a derivative of the original library.  The ordinary
76
General Public License therefore permits such linking only if the
77
entire combination fits its criteria of freedom.  The Lesser General
78
Public License permits more lax criteria for linking other code with
79
the library.
80

  
81
  We call this license the "Lesser" General Public License because it
82
does Less to protect the user's freedom than the ordinary General
83
Public License.  It also provides other free software developers Less
84
of an advantage over competing non-free programs.  These disadvantages
85
are the reason we use the ordinary General Public License for many
86
libraries.  However, the Lesser license provides advantages in certain
87
special circumstances.
88

  
89
  For example, on rare occasions, there may be a special need to
90
encourage the widest possible use of a certain library, so that it becomes
91
a de-facto standard.  To achieve this, non-free programs must be
92
allowed to use the library.  A more frequent case is that a free
93
library does the same job as widely used non-free libraries.  In this
94
case, there is little to gain by limiting the free library to free
95
software only, so we use the Lesser General Public License.
96

  
97
  In other cases, permission to use a particular library in non-free
98
programs enables a greater number of people to use a large body of
99
free software.  For example, permission to use the GNU C Library in
100
non-free programs enables many more people to use the whole GNU
101
operating system, as well as its variant, the GNU/Linux operating
102
system.
103

  
104
  Although the Lesser General Public License is Less protective of the
105
users' freedom, it does ensure that the user of a program that is
106
linked with the Library has the freedom and the wherewithal to run
107
that program using a modified version of the Library.
108

  
109
  The precise terms and conditions for copying, distribution and
110
modification follow.  Pay close attention to the difference between a
111
"work based on the library" and a "work that uses the library".  The
112
former contains code derived from the library, whereas the latter must
113
be combined with the library in order to run.
114

115
		  GNU LESSER GENERAL PUBLIC LICENSE
116
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
117

  
118
  0. This License Agreement applies to any software library or other
119
program which contains a notice placed by the copyright holder or
120
other authorized party saying it may be distributed under the terms of
121
this Lesser General Public License (also called "this License").
122
Each licensee is addressed as "you".
123

  
124
  A "library" means a collection of software functions and/or data
125
prepared so as to be conveniently linked with application programs
126
(which use some of those functions and data) to form executables.
127

  
128
  The "Library", below, refers to any such software library or work
129
which has been distributed under these terms.  A "work based on the
130
Library" means either the Library or any derivative work under
131
copyright law: that is to say, a work containing the Library or a
132
portion of it, either verbatim or with modifications and/or translated
133
straightforwardly into another language.  (Hereinafter, translation is
134
included without limitation in the term "modification".)
135

  
136
  "Source code" for a work means the preferred form of the work for
137
making modifications to it.  For a library, complete source code means
138
all the source code for all modules it contains, plus any associated
139
interface definition files, plus the scripts used to control compilation
140
and installation of the library.
141

  
142
  Activities other than copying, distribution and modification are not
143
covered by this License; they are outside its scope.  The act of
144
running a program using the Library is not restricted, and output from
145
such a program is covered only if its contents constitute a work based
146
on the Library (independent of the use of the Library in a tool for
147
writing it).  Whether that is true depends on what the Library does
148
and what the program that uses the Library does.
149
  
150
  1. You may copy and distribute verbatim copies of the Library's
151
complete source code as you receive it, in any medium, provided that
152
you conspicuously and appropriately publish on each copy an
153
appropriate copyright notice and disclaimer of warranty; keep intact
154
all the notices that refer to this License and to the absence of any
155
warranty; and distribute a copy of this License along with the
156
Library.
157

  
158
  You may charge a fee for the physical act of transferring a copy,
159
and you may at your option offer warranty protection in exchange for a
160
fee.
161

162
  2. You may modify your copy or copies of the Library or any portion
163
of it, thus forming a work based on the Library, and copy and
164
distribute such modifications or work under the terms of Section 1
165
above, provided that you also meet all of these conditions:
166

  
167
    a) The modified work must itself be a software library.
168

  
169
    b) You must cause the files modified to carry prominent notices
170
    stating that you changed the files and the date of any change.
171

  
172
    c) You must cause the whole of the work to be licensed at no
173
    charge to all third parties under the terms of this License.
174

  
175
    d) If a facility in the modified Library refers to a function or a
176
    table of data to be supplied by an application program that uses
177
    the facility, other than as an argument passed when the facility
178
    is invoked, then you must make a good faith effort to ensure that,
179
    in the event an application does not supply such function or
180
    table, the facility still operates, and performs whatever part of
181
    its purpose remains meaningful.
182

  
183
    (For example, a function in a library to compute square roots has
184
    a purpose that is entirely well-defined independent of the
185
    application.  Therefore, Subsection 2d requires that any
186
    application-supplied function or table used by this function must
187
    be optional: if the application does not supply it, the square
188
    root function must still compute square roots.)
189

  
190
These requirements apply to the modified work as a whole.  If
191
identifiable sections of that work are not derived from the Library,
192
and can be reasonably considered independent and separate works in
193
themselves, then this License, and its terms, do not apply to those
194
sections when you distribute them as separate works.  But when you
195
distribute the same sections as part of a whole which is a work based
196
on the Library, the distribution of the whole must be on the terms of
197
this License, whose permissions for other licensees extend to the
198
entire whole, and thus to each and every part regardless of who wrote
199
it.
200

  
201
Thus, it is not the intent of this section to claim rights or contest
202
your rights to work written entirely by you; rather, the intent is to
203
exercise the right to control the distribution of derivative or
204
collective works based on the Library.
205

  
206
In addition, mere aggregation of another work not based on the Library
207
with the Library (or with a work based on the Library) on a volume of
208
a storage or distribution medium does not bring the other work under
209
the scope of this License.
210

  
211
  3. You may opt to apply the terms of the ordinary GNU General Public
212
License instead of this License to a given copy of the Library.  To do
213
this, you must alter all the notices that refer to this License, so
214
that they refer to the ordinary GNU General Public License, version 2,
215
instead of to this License.  (If a newer version than version 2 of the
216
ordinary GNU General Public License has appeared, then you can specify
217
that version instead if you wish.)  Do not make any other change in
218
these notices.
219

220
  Once this change is made in a given copy, it is irreversible for
221
that copy, so the ordinary GNU General Public License applies to all
222
subsequent copies and derivative works made from that copy.
223

  
224
  This option is useful when you wish to copy part of the code of
225
the Library into a program that is not a library.
226

  
227
  4. You may copy and distribute the Library (or a portion or
228
derivative of it, under Section 2) in object code or executable form
229
under the terms of Sections 1 and 2 above provided that you accompany
230
it with the complete corresponding machine-readable source code, which
231
must be distributed under the terms of Sections 1 and 2 above on a
232
medium customarily used for software interchange.
233

  
234
  If distribution of object code is made by offering access to copy
235
from a designated place, then offering equivalent access to copy the
236
source code from the same place satisfies the requirement to
237
distribute the source code, even though third parties are not
238
compelled to copy the source along with the object code.
239

  
240
  5. A program that contains no derivative of any portion of the
241
Library, but is designed to work with the Library by being compiled or
242
linked with it, is called a "work that uses the Library".  Such a
243
work, in isolation, is not a derivative work of the Library, and
244
therefore falls outside the scope of this License.
245

  
246
  However, linking a "work that uses the Library" with the Library
247
creates an executable that is a derivative of the Library (because it
248
contains portions of the Library), rather than a "work that uses the
249
library".  The executable is therefore covered by this License.
250
Section 6 states terms for distribution of such executables.
251

  
252
  When a "work that uses the Library" uses material from a header file
253
that is part of the Library, the object code for the work may be a
254
derivative work of the Library even though the source code is not.
255
Whether this is true is especially significant if the work can be
256
linked without the Library, or if the work is itself a library.  The
257
threshold for this to be true is not precisely defined by law.
258

  
259
  If such an object file uses only numerical parameters, data
260
structure layouts and accessors, and small macros and small inline
261
functions (ten lines or less in length), then the use of the object
262
file is unrestricted, regardless of whether it is legally a derivative
263
work.  (Executables containing this object code plus portions of the
264
Library will still fall under Section 6.)
265

  
266
  Otherwise, if the work is a derivative of the Library, you may
267
distribute the object code for the work under the terms of Section 6.
268
Any executables containing that work also fall under Section 6,
269
whether or not they are linked directly with the Library itself.
270

271
  6. As an exception to the Sections above, you may also combine or
272
link a "work that uses the Library" with the Library to produce a
273
work containing portions of the Library, and distribute that work
274
under terms of your choice, provided that the terms permit
275
modification of the work for the customer's own use and reverse
276
engineering for debugging such modifications.
277

  
278
  You must give prominent notice with each copy of the work that the
279
Library is used in it and that the Library and its use are covered by
280
this License.  You must supply a copy of this License.  If the work
281
during execution displays copyright notices, you must include the
282
copyright notice for the Library among them, as well as a reference
283
directing the user to the copy of this License.  Also, you must do one
284
of these things:
285

  
286
    a) Accompany the work with the complete corresponding
287
    machine-readable source code for the Library including whatever
288
    changes were used in the work (which must be distributed under
289
    Sections 1 and 2 above); and, if the work is an executable linked
290
    with the Library, with the complete machine-readable "work that
291
    uses the Library", as object code and/or source code, so that the
292
    user can modify the Library and then relink to produce a modified
293
    executable containing the modified Library.  (It is understood
294
    that the user who changes the contents of definitions files in the
295
    Library will not necessarily be able to recompile the application
296
    to use the modified definitions.)
297

  
298
    b) Use a suitable shared library mechanism for linking with the
299
    Library.  A suitable mechanism is one that (1) uses at run time a
300
    copy of the library already present on the user's computer system,
301
    rather than copying library functions into the executable, and (2)
302
    will operate properly with a modified version of the library, if
303
    the user installs one, as long as the modified version is
304
    interface-compatible with the version that the work was made with.
305

  
306
    c) Accompany the work with a written offer, valid for at
307
    least three years, to give the same user the materials
308
    specified in Subsection 6a, above, for a charge no more
309
    than the cost of performing this distribution.
310

  
311
    d) If distribution of the work is made by offering access to copy
312
    from a designated place, offer equivalent access to copy the above
313
    specified materials from the same place.
314

  
315
    e) Verify that the user has already received a copy of these
316
    materials or that you have already sent this user a copy.
317

  
318
  For an executable, the required form of the "work that uses the
319
Library" must include any data and utility programs needed for
320
reproducing the executable from it.  However, as a special exception,
321
the materials to be distributed need not include anything that is
322
normally distributed (in either source or binary form) with the major
323
components (compiler, kernel, and so on) of the operating system on
324
which the executable runs, unless that component itself accompanies
325
the executable.
326

  
327
  It may happen that this requirement contradicts the license
328
restrictions of other proprietary libraries that do not normally
329
accompany the operating system.  Such a contradiction means you cannot
330
use both them and the Library together in an executable that you
331
distribute.
332

333
  7. You may place library facilities that are a work based on the
334
Library side-by-side in a single library together with other library
335
facilities not covered by this License, and distribute such a combined
336
library, provided that the separate distribution of the work based on
337
the Library and of the other library facilities is otherwise
338
permitted, and provided that you do these two things:
339

  
340
    a) Accompany the combined library with a copy of the same work
341
    based on the Library, uncombined with any other library
342
    facilities.  This must be distributed under the terms of the
343
    Sections above.
344

  
345
    b) Give prominent notice with the combined library of the fact
346
    that part of it is a work based on the Library, and explaining
347
    where to find the accompanying uncombined form of the same work.
348

  
349
  8. You may not copy, modify, sublicense, link with, or distribute
350
the Library except as expressly provided under this License.  Any
351
attempt otherwise to copy, modify, sublicense, link with, or
352
distribute the Library is void, and will automatically terminate your
353
rights under this License.  However, parties who have received copies,
354
or rights, from you under this License will not have their licenses
355
terminated so long as such parties remain in full compliance.
356

  
357
  9. You are not required to accept this License, since you have not
358
signed it.  However, nothing else grants you permission to modify or
359
distribute the Library or its derivative works.  These actions are
360
prohibited by law if you do not accept this License.  Therefore, by
361
modifying or distributing the Library (or any work based on the
362
Library), you indicate your acceptance of this License to do so, and
363
all its terms and conditions for copying, distributing or modifying
364
the Library or works based on it.
365

  
366
  10. Each time you redistribute the Library (or any work based on the
367
Library), the recipient automatically receives a license from the
368
original licensor to copy, distribute, link with or modify the Library
369
subject to these terms and conditions.  You may not impose any further
370
restrictions on the recipients' exercise of the rights granted herein.
371
You are not responsible for enforcing compliance by third parties with
372
this License.
373

374
  11. If, as a consequence of a court judgment or allegation of patent
375
infringement or for any other reason (not limited to patent issues),
376
conditions are imposed on you (whether by court order, agreement or
377
otherwise) that contradict the conditions of this License, they do not
378
excuse you from the conditions of this License.  If you cannot
379
distribute so as to satisfy simultaneously your obligations under this
380
License and any other pertinent obligations, then as a consequence you
381
may not distribute the Library at all.  For example, if a patent
382
license would not permit royalty-free redistribution of the Library by
383
all those who receive copies directly or indirectly through you, then
384
the only way you could satisfy both it and this License would be to
385
refrain entirely from distribution of the Library.
386

  
387
If any portion of this section is held invalid or unenforceable under any
388
particular circumstance, the balance of the section is intended to apply,
389
and the section as a whole is intended to apply in other circumstances.
390

  
391
It is not the purpose of this section to induce you to infringe any
392
patents or other property right claims or to contest validity of any
393
such claims; this section has the sole purpose of protecting the
394
integrity of the free software distribution system which is
395
implemented by public license practices.  Many people have made
396
generous contributions to the wide range of software distributed
397
through that system in reliance on consistent application of that
398
system; it is up to the author/donor to decide if he or she is willing
399
to distribute software through any other system and a licensee cannot
400
impose that choice.
401

  
402
This section is intended to make thoroughly clear what is believed to
403
be a consequence of the rest of this License.
404

  
405
  12. If the distribution and/or use of the Library is restricted in
406
certain countries either by patents or by copyrighted interfaces, the
407
original copyright holder who places the Library under this License may add
408
an explicit geographical distribution limitation excluding those countries,
409
so that distribution is permitted only in or among countries not thus
410
excluded.  In such case, this License incorporates the limitation as if
411
written in the body of this License.
412

  
413
  13. The Free Software Foundation may publish revised and/or new
414
versions of the Lesser General Public License from time to time.
415
Such new versions will be similar in spirit to the present version,
416
but may differ in detail to address new problems or concerns.
417

  
418
Each version is given a distinguishing version number.  If the Library
419
specifies a version number of this License which applies to it and
420
"any later version", you have the option of following the terms and
421
conditions either of that version or of any later version published by
422
the Free Software Foundation.  If the Library does not specify a
423
license version number, you may choose any version ever published by
424
the Free Software Foundation.
425

426
  14. If you wish to incorporate parts of the Library into other free
427
programs whose distribution conditions are incompatible with these,
428
write to the author to ask for permission.  For software which is
429
copyrighted by the Free Software Foundation, write to the Free
430
Software Foundation; we sometimes make exceptions for this.  Our
431
decision will be guided by the two goals of preserving the free status
432
of all derivatives of our free software and of promoting the sharing
433
and reuse of software generally.
434

           How to Apply These Terms to Your New Libraries
461

  
462
  If you develop a new library, and you want it to be of the greatest
463
possible use to the public, we recommend making it free software that
464
everyone can redistribute and change.  You can do so by permitting
465
redistribution under these terms (or, alternatively, under the terms of the
466
ordinary General Public License).
467

  
468
  To apply these terms, attach the following notices to the library.  It is
469
safest to attach them to the start of each source file to most effectively
470
convey the exclusion of warranty; and each file should have at least the
471
"copyright" line and a pointer to where the full notice is found.
472

  
473
    <one line to give the library's name and a brief idea of what it does.>
474
    Copyright (C) <year>  <name of author>
475

  
476
    This library is free software; you can redistribute it and/or
477
    modify it under the terms of the GNU Lesser General Public
478
    License as published by the Free Software Foundation; either
479
    version 2.1 of the License, or (at your option) any later version.
480

  
481
    This library is distributed in the hope that it will be useful,
482
    but WITHOUT ANY WARRANTY; without even the implied warranty of
483
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
484
    Lesser General Public License for more details.
485

  
486
    You should have received a copy of the GNU Lesser General Public
487
    License along with this library; if not, write to the Free Software
488
    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
489

  
490
Also add information on how to contact you by electronic and paper mail.
491

  
492
You should also get your employer (if you work as a programmer) or your
493
school, if any, to sign a "copyright disclaimer" for the library, if
494
necessary.  Here is a sample; alter the names:
495

In a modular setting:
10
# lustrec <filename.lus>
11
will generate filename.c and filename.h
12

  
13
With a main node:
14
# lustrec -node <main_node> <filename.lus>
15
will generate the same two files, but filename.c will contains a main function
16

  
17
With a main node, with a static memory allocation scheme:
18
# lustrec -node <main_node> -static <filename.lus>
19
same as above, but main function will statically allocate memory
20

  
21
To compile it:
22
# gcc -Iinclude filename.c
23
where include links to the include folder
24

  
25
To run it with the generated main function:
26
- compile the io_frontend.o
27
# gcc -c include/io_frontend.c
28
# gcc -Iinclude -o target_name io_frontend.c filename.c
