6 Everyone is permitted to copy and distribute verbatim copies
7 of this license document, but changing it is not allowed.

9 Preamble
10
11 The licenses for most software are designed to take away your
12 freedom to share and change it. By contrast, the GNU General Public
13 License is intended to guarantee your freedom to share and change free
14 software--to make sure the software is free for all its users. This
15 General Public License applies to most of the Free Software
16 Foundation's software and to any other program whose authors commit to
17 using it. (Some other Free Software Foundation software is covered by
18 the GNU Library General Public License instead.) You can apply it to
19 your programs, too.
20
21 When we speak of free software, we are referring to freedom, not
22 price. Our General Public Licenses are designed to make sure that you
23 have the freedom to distribute copies of free software (and charge for
24 this service if you wish), that you receive source code or can get it
25 if you want it, that you can change the software or use pieces of it
26 in new free programs; and that you know you can do these things.
27
28 To protect your rights, we need to make restrictions that forbid
29 anyone to deny you these rights or to ask you to surrender the rights.
30 These restrictions translate to certain responsibilities for you if you
31 distribute copies of the software, or if you modify it.
32
33 For example, if you distribute copies of such a program, whether
34 gratis or for a fee, you must give the recipients all the rights that
35 you have. You must make sure that they, too, receive or can get the
36 source code. And you must show them these terms so they know their
37 rights.
38
39 We protect your rights with two steps: (1) copyright the software, and
40 (2) offer you this license which gives you legal permission to copy,
41 distribute and/or modify the software.
42
43 Also, for each author's protection and ours, we want to make certain
44 that everyone understands that there is no warranty for this free
45 software. If the software is modified by someone else and passed on, we
46 want its recipients to know that what they have is not the original, so
47 that any problems introduced by others will not reflect on the original
48 authors' reputations.
49
50 Finally, any free program is threatened constantly by software
51 patents. We wish to avoid the danger that redistributors of a free
52 program will individually obtain patent licenses, in effect making the
53 program proprietary. To prevent this, we have made it clear that any
54 patent must be licensed for everyone's free use or not licensed at all.
55
56 The precise terms and conditions for copying, distribution and
57 modification follow.
58
59 GNU GENERAL PUBLIC LICENSE
60 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
61
62 0. This License applies to any program or other work which contains
63 a notice placed by the copyright holder saying it may be distributed
64 under the terms of this General Public License. The "Program", below,
65 refers to any such program or work, and a "work based on the Program"
66 means either the Program or any derivative work under copyright law:
67 that is to say, a work containing the Program or a portion of it,
68 either verbatim or with modifications and/or translated into another
69 language. (Hereinafter, translation is included without limitation in
70 the term "modification".) Each licensee is addressed as "you".
71
72 Activities other than copying, distribution and modification are not
73 covered by this License; they are outside its scope. The act of
74 running the Program is not restricted, and the output from the Program
75 is covered only if its contents constitute a work based on the
76 Program (independent of having been made by running the Program).
77 Whether that is true depends on what the Program does.
78
79 1. You may copy and distribute verbatim copies of the Program's
80 source code as you receive it, in any medium, provided that you
81 conspicuously and appropriately publish on each copy an appropriate
82 copyright notice and disclaimer of warranty; keep intact all the
83 notices that refer to this License and to the absence of any warranty;
84 and give any other recipients of the Program a copy of this License
85 along with the Program.
86
87 You may charge a fee for the physical act of transferring a copy, and
88 you may at your option offer warranty protection in exchange for a fee.
89
90 2. You may modify your copy or copies of the Program or any portion
91 of it, thus forming a work based on the Program, and copy and
92 distribute such modifications or work under the terms of Section 1
93 above, provided that you also meet all of these conditions:
94
95 a) You must cause the modified files to carry prominent notices
96 stating that you changed the files and the date of any change.
97
98 b) You must cause any work that you distribute or publish, that in
99 whole or in part contains or is derived from the Program or any
100 part thereof, to be licensed as a whole at no charge to all third
101 parties under the terms of this License.
102
103 c) If the modified program normally reads commands interactively
104 when run, you must cause it, when started running for such
105 interactive use in the most ordinary way, to print or display an
106 announcement including an appropriate copyright notice and a
107 notice that there is no warranty (or else, saying that you provide
108 a warranty) and that users may redistribute the program under
109 these conditions, and telling the user how to view a copy of this
110 License. (Exception: if the Program itself is interactive but
111 does not normally print such an announcement, your work based on
112 the Program is not required to print an announcement.)
113
114 These requirements apply to the modified work as a whole. If
115 identifiable sections of that work are not derived from the Program,
116 and can be reasonably considered independent and separate works in
117 themselves, then this License, and its terms, do not apply to those
118 sections when you distribute them as separate works. But when you
119 distribute the same sections as part of a whole which is a work based
120 on the Program, the distribution of the whole must be on the terms of
121 this License, whose permissions for other licensees extend to the
122 entire whole, and thus to each and every part regardless of who wrote it.
123
124 Thus, it is not the intent of this section to claim rights or contest
125 your rights to work written entirely by you; rather, the intent is to
126 exercise the right to control the distribution of derivative or
127 collective works based on the Program.
128
129 In addition, mere aggregation of another work not based on the Program
130 with the Program (or with a work based on the Program) on a volume of
131 a storage or distribution medium does not bring the other work under
132 the scope of this License.
133
134 3. You may copy and distribute the Program (or a work based on it,
135 under Section 2) in object code or executable form under the terms of
136 Sections 1 and 2 above provided that you also do one of the following:
137
138 a) Accompany it with the complete corresponding machine-readable
139 source code, which must be distributed under the terms of Sections
140 1 and 2 above on a medium customarily used for software interchange; or,
141
142 b) Accompany it with a written offer, valid for at least three
143 years, to give any third party, for a charge no more than your
144 cost of physically performing source distribution, a complete
145 machine-readable copy of the corresponding source code, to be
146 distributed under the terms of Sections 1 and 2 above on a medium
147 customarily used for software interchange; or,
148
149 c) Accompany it with the information you received as to the offer
150 to distribute corresponding source code. (This alternative is
151 allowed only for noncommercial distribution and only if you
152 received the program in object code or executable form with such
153 an offer, in accord with Subsection b above.)
154
155 The source code for a work means the preferred form of the work for
156 making modifications to it. For an executable work, complete source
157 code means all the source code for all modules it contains, plus any
158 associated interface definition files, plus the scripts used to
159 control compilation and installation of the executable. However, as a
160 special exception, the source code distributed need not include
161 anything that is normally distributed (in either source or binary
162 form) with the major components (compiler, kernel, and so on) of the
163 operating system on which the executable runs, unless that component
164 itself accompanies the executable.
165
166 If distribution of executable or object code is made by offering
167 access to copy from a designated place, then offering equivalent
168 access to copy the source code from the same place counts as
169 distribution of the source code, even though third parties are not
170 compelled to copy the source along with the object code.
171
172 4. You may not copy, modify, sublicense, or distribute the Program
173 except as expressly provided under this License. Any attempt
174 otherwise to copy, modify, sublicense or distribute the Program is
175 void, and will automatically terminate your rights under this License.
176 However, parties who have received copies, or rights, from you under
177 this License will not have their licenses terminated so long as such
178 parties remain in full compliance.
179
180 5. You are not required to accept this License, since you have not
181 signed it. However, nothing else grants you permission to modify or
182 distribute the Program or its derivative works. These actions are
183 prohibited by law if you do not accept this License. Therefore, by
184 modifying or distributing the Program (or any work based on the
185 Program), you indicate your acceptance of this License to do so, and
186 all its terms and conditions for copying, distributing or modifying
187 the Program or works based on it.
188
189 6. Each time you redistribute the Program (or any work based on the
190 Program), the recipient automatically receives a license from the
191 original licensor to copy, distribute or modify the Program subject to
192 these terms and conditions. You may not impose any further
193 restrictions on the recipients' exercise of the rights granted herein.
194 You are not responsible for enforcing compliance by third parties to
195 this License.
196
197 7. If, as a consequence of a court judgment or allegation of patent
198 infringement or for any other reason (not limited to patent issues),
199 conditions are imposed on you (whether by court order, agreement or
200 otherwise) that contradict the conditions of this License, they do not
201 excuse you from the conditions of this License. If you cannot
202 distribute so as to satisfy simultaneously your obligations under this
203 License and any other pertinent obligations, then as a consequence you
204 may not distribute the Program at all. For example, if a patent
205 license would not permit royalty-free redistribution of the Program by
206 all those who receive copies directly or indirectly through you, then
207 the only way you could satisfy both it and this License would be to
208 refrain entirely from distribution of the Program.
209
210 If any portion of this section is held invalid or unenforceable under
211 any particular circumstance, the balance of the section is intended to
212 apply and the section as a whole is intended to apply in other
213 circumstances.
214
215 It is not the purpose of this section to induce you to infringe any
216 patents or other property right claims or to contest validity of any
217 such claims; this section has the sole purpose of protecting the
218 integrity of the free software distribution system, which is
219 implemented by public license practices. Many people have made
220 generous contributions to the wide range of software distributed
221 through that system in reliance on consistent application of that
222 system; it is up to the author/donor to decide if he or she is willing
223 to distribute software through any other system and a licensee cannot
224 impose that choice.
225
226 This section is intended to make thoroughly clear what is believed to
227 be a consequence of the rest of this License.
228
229 8. If the distribution and/or use of the Program is restricted in
230 certain countries either by patents or by copyrighted interfaces, the
231 original copyright holder who places the Program under this License
232 may add an explicit geographical distribution limitation excluding
233 those countries, so that distribution is permitted only in or among
234 countries not thus excluded. In such case, this License incorporates
235 the limitation as if written in the body of this License.
236
237 9. The Free Software Foundation may publish revised and/or new versions
238 of the General Public License from time to time. Such new versions will
239 be similar in spirit to the present version, but may differ in detail to
240 address new problems or concerns.
241
242 Each version is given a distinguishing version number. If the Program
243 specifies a version number of this License which applies to it and "any
244 later version", you have the option of following the terms and conditions
245 either of that version or of any later version published by the Free
246 Software Foundation. If the Program does not specify a version number of
247 this License, you may choose any version ever published by the Free Software
248 Foundation.
249
250 10. If you wish to incorporate parts of the Program into other free
251 programs whose distribution conditions are different, write to the author
252 to ask for permission. For software which is copyrighted by the Free
253 Software Foundation, write to the Free Software Foundation; we sometimes
254 make exceptions for this. Our decision will be guided by the two goals
255 of preserving the free status of all derivatives of our free software and
256 of promoting the sharing and reuse of software generally.
257
258 NO WARRANTY
259
260 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
261 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
262 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
263 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
264 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
265 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
266 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
267 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
268 REPAIR OR CORRECTION.
269
270 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
271 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
272 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
273 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
274 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
275 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
276 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
277 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
278 POSSIBILITY OF SUCH DAMAGES.
279
280 END OF TERMS AND CONDITIONS
281
282 How to Apply These Terms to Your New Programs
283
284 If you develop a new program, and you want it to be of the greatest
285 possible use to the public, the best way to achieve this is to make it
286 free software which everyone can redistribute and change under these terms.
287
288 To do so, attach the following notices to the program. It is safest
289 to attach them to the start of each source file to most effectively
290 convey the exclusion of warranty; and each file should have at least
291 the "copyright" line and a pointer to where the full notice is found.
292
293 <one line to give the program's name and a brief idea of what it does.>
294 Copyright (C) <year> <name of author>
295
296 This program is free software; you can redistribute it and/or modify
297 it under the terms of the GNU General Public License as published by
298 the Free Software Foundation; either version 2 of the License, or
299 (at your option) any later version.
300
301 This program is distributed in the hope that it will be useful,
302 but WITHOUT ANY WARRANTY; without even the implied warranty of
303 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
304 GNU General Public License for more details.
305
306 You should have received a copy of the GNU General Public License
307 along with this program; if not, write to the Free Software
308 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
309
310
311 Also add information on how to contact you by electronic and paper mail.
312
313 If the program is interactive, make it output a short notice like this
314 when it starts in an interactive mode:
315
316 Gnomovision version 69, Copyright (C) year name of author
317 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
318 This is free software, and you are welcome to redistribute it
319 under certain conditions; type `show c' for details.
320
321 The hypothetical commands `show w' and `show c' should show the appropriate
322 parts of the General Public License. Of course, the commands you use may
323 be called something other than `show w' and `show c'; they could even be
324 mouse-clicks or menu items--whatever suits your program.
325
326 You should also get your employer (if you work as a programmer) or your
327 school, if any, to sign a "copyright disclaimer" for the program, if
328 necessary. Here is a sample; alter the names:
329
330 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
331 `Gnomovision' (which makes passes at compilers) written by James Hacker.
332
333 <signature of Ty Coon>, 1 April 1989
334 Ty Coon, President of Vice
335
336 This General Public License does not permit incorporating your program into
337 proprietary programs. If your program is a subroutine library, you may
338 consider it more useful to permit linking proprietary applications with the
339 library. If this is what you want to do, use the GNU Library General
340 Public License instead of this License.

8 unlimited permission to copy, distribute and modify it.

10 Basic Installation
11 ==================
12
13 Briefly, the shell commands `./configure; make; make install' should
14 configure, build, and install this package. The following
15 more-detailed instructions are generic; see the `README' file for
16 instructions specific to this package.
17
18 The `configure' shell script attempts to guess correct values for
19 various system-dependent variables used during compilation. It uses
20 those values to create a `Makefile' in each directory of the package.
21 It may also create one or more `.h' files containing system-dependent
22 definitions. Finally, it creates a shell script `config.status' that
23 you can run in the future to recreate the current configuration, and a
24 file `config.log' containing compiler output (useful mainly for
25 debugging `configure').
26
27 It can also use an optional file (typically called `config.cache'
28 and enabled with `--cache-file=config.cache' or simply `-C') that saves
29 the results of its tests to speed up reconfiguring. Caching is
30 disabled by default to prevent problems with accidental use of stale
31 cache files.
32
33 If you need to do unusual things to compile the package, please try
34 to figure out how `configure' could check whether to do them, and mail
35 diffs or instructions to the address given in the `README' so they can
36 be considered for the next release. If you are using the cache, and at
37 some point `config.cache' contains results you don't want to keep, you
38 may remove or edit it.
39
40 The file `configure.ac' (or `configure.in') is used to create
41 `configure' by a program called `autoconf'. You need `configure.ac' if
42 you want to change it or regenerate `configure' using a newer version
43 of `autoconf'.
44
45 The simplest way to compile this package is:
46
47 1. `cd' to the directory containing the package's source code and type
48 `./configure' to configure the package for your system.
49
50 Running `configure' might take a while. While running, it prints
51 some messages telling which features it is checking for.
52
53 2. Type `make' to compile the package.
54
55 3. Optionally, type `make check' to run any self-tests that come with
56 the package.
57
58 4. Type `make install' to install the programs and any data files and
59 documentation.
60
61 5. You can remove the program binaries and object files from the
62 source code directory by typing `make clean'. To also remove the
63 files that `configure' created (so you can compile the package for
64 a different kind of computer), type `make distclean'. There is
65 also a `make maintainer-clean' target, but that is intended mainly
66 for the package's developers. If you use it, you may have to get
67 all sorts of other programs in order to regenerate files that came
68 with the distribution.
69
70 6. Often, you can also type `make uninstall' to remove the installed
71 files again.
72
73 Compilers and Options
74 =====================
75
76 Some systems require unusual options for compilation or linking that the
77 `configure' script does not know about. Run `./configure --help' for
78 details on some of the pertinent environment variables.
79
80 You can give `configure' initial values for configuration parameters
81 by setting variables in the command line or in the environment. Here
82 is an example:
83
84 ./configure CC=c99 CFLAGS=-g LIBS=-lposix
85
86 *Note Defining Variables::, for more details.
87
88 Compiling For Multiple Architectures
89 ====================================
90
91 You can compile the package for more than one kind of computer at the
92 same time, by placing the object files for each architecture in their
93 own directory. To do this, you can use GNU `make'. `cd' to the
94 directory where you want the object files and executables to go and run
95 the `configure' script. `configure' automatically checks for the
96 source code in the directory that `configure' is in and in `..'.
97
98 With a non-GNU `make', it is safer to compile the package for one
99 architecture at a time in the source code directory. After you have
100 installed the package for one architecture, use `make distclean' before
101 reconfiguring for another architecture.
102
103 Installation Names
104 ==================
105
106 By default, `make install' installs the package's commands under
107 `/usr/local/bin', include files under `/usr/local/include', etc. You
108 can specify an installation prefix other than `/usr/local' by giving
109 `configure' the option `--prefix=PREFIX'.
110
111 You can specify separate installation prefixes for
112 architecture-specific files and architecture-independent files. If you
113 pass the option `--exec-prefix=PREFIX' to `configure', the package uses
114 PREFIX as the prefix for installing programs and libraries.
115 Documentation and other data files still use the regular prefix.
116
117 In addition, if you use an unusual directory layout you can give
118 options like `--bindir=DIR' to specify different values for particular
119 kinds of files. Run `configure --help' for a list of the directories
120 you can set and what kinds of files go in them.
121
122 If the package supports it, you can cause programs to be installed
123 with an extra prefix or suffix on their names by giving `configure' the
124 option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
125
126 Optional Features
127 =================
128
129 Some packages pay attention to `--enable-FEATURE' options to
130 `configure', where FEATURE indicates an optional part of the package.
131 They may also pay attention to `--with-PACKAGE' options, where PACKAGE
132 is something like `gnu-as' or `x' (for the X Window System). The
133 `README' should mention any `--enable-' and `--with-' options that the
134 package recognizes.
135
136 For packages that use the X Window System, `configure' can usually
137 find the X include and library files automatically, but if it doesn't,
138 you can use the `configure' options `--x-includes=DIR' and
139 `--x-libraries=DIR' to specify their locations.
140
141 Specifying the System Type
142 ==========================
143
144 There may be some features `configure' cannot figure out automatically,
145 but needs to determine by the type of machine the package will run on.
146 Usually, assuming the package is built to be run on the _same_
147 architectures, `configure' can figure that out, but if it prints a
148 message saying it cannot guess the machine type, give it the
149 `--build=TYPE' option. TYPE can either be a short name for the system
150 type, such as `sun4', or a canonical name which has the form:
151
152 CPU-COMPANY-SYSTEM
153
154 where SYSTEM can have one of these forms:
155
156 OS KERNEL-OS
157
158 See the file `config.sub' for the possible values of each field. If
159 `config.sub' isn't included in this package, then this package doesn't
160 need to know the machine type.
161
162 If you are _building_ compiler tools for cross-compiling, you should
163 use the option `--target=TYPE' to select the type of system they will
164 produce code for.
165
166 If you want to _use_ a cross compiler, that generates code for a
167 platform different from the build platform, you should specify the
168 "host" platform (i.e., that on which the generated programs will
169 eventually be run) with `--host=TYPE'.
170
171 Sharing Defaults
172 ================
173
174 If you want to set default values for `configure' scripts to share, you
175 can create a site shell script called `config.site' that gives default
176 values for variables like `CC', `cache_file', and `prefix'.
177 `configure' looks for `PREFIX/share/config.site' if it exists, then
178 `PREFIX/etc/config.site' if it exists. Or, you can set the
179 `CONFIG_SITE' environment variable to the location of the site script.
180 A warning: not all `configure' scripts look for a site script.
181
182 Defining Variables
183 ==================
184
185 Variables not defined in a site shell script can be set in the
186 environment passed to `configure'. However, some packages may run
187 configure again during the build, and the customized values of these
188 variables may be lost. In order to avoid this problem, you should set
189 them in the `configure' command line, using `VAR=value'. For example:
190
191 ./configure CC=/usr/local2/bin/gcc
192
193 causes the specified `gcc' to be used as the C compiler (unless it is
194 overridden in the site shell script).
195
196 Unfortunately, this technique does not work for `CONFIG_SHELL' due to
197 an Autoconf bug. Until the bug is fixed you can use this workaround:
198
199 CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
200
201 `configure' Invocation
202 ======================
203
204 `configure' recognizes the following options to control how it operates.
205
206 `--help'
207 `-h'
208 Print a summary of the options to `configure', and exit.
209
210 `--version'
211 `-V'
212 Print the version of Autoconf used to generate the `configure'
213 script, and exit.
214
215 `--cache-file=FILE'
216 Enable the cache: use and save the results of the tests in FILE,
217 traditionally `config.cache'. FILE defaults to `/dev/null' to
218 disable caching.
219
220 `--config-cache'
221 `-C'
222 Alias for `--cache-file=config.cache'.
223
224 `--quiet'
225 `--silent'
226 `-q'
227 Do not print messages saying which checks are being made. To
228 suppress all normal output, redirect it to `/dev/null' (any error
229 messages will still be shown).
230
231 `--srcdir=DIR'
232 Look for the package's source code in directory DIR. Usually
233 `configure' can determine that directory automatically.
234
235 `configure' also accepts some other, not widely useful, options. Run
236 `configure --help' for more details.
