   9                             Preamble
  10
  11   The GNU General Public License is a free, copyleft license for
  12 software and other kinds of works.
  13
  14   The licenses for most software and other practical works are designed
  15 to take away your freedom to share and change the works.  By contrast,
  16 the GNU General Public License is intended to guarantee your freedom to
  17 share and change all versions of a program--to make sure it remains free
  18 software for all its users.  We, the Free Software Foundation, use the
  19 GNU General Public License for most of our software; it applies also to
  20 any other work released this way by its authors.  You can apply it to
  21 your programs, too.
  22
  23   When we speak of free software, we are referring to freedom, not
  24 price.  Our General Public Licenses are designed to make sure that you
  25 have the freedom to distribute copies of free software (and charge for
  26 them if you wish), that you receive source code or can get it if you
  27 want it, that you can change the software or use pieces of it in new
  28 free programs, and that you know you can do these things.
  29
  30   To protect your rights, we need to prevent others from denying you
  31 these rights or asking you to surrender the rights.  Therefore, you have
  32 certain responsibilities if you distribute copies of the software, or if
  33 you modify it: responsibilities to respect the freedom of others.
  34
  35   For example, if you distribute copies of such a program, whether
  36 gratis or for a fee, you must pass on to the recipients the same
  37 freedoms that you received.  You must make sure that they, too, receive
  38 or can get the source code.  And you must show them these terms so they
  39 know their rights.
  40
  41   Developers that use the GNU GPL protect your rights with two steps:
  42 (1) assert copyright on the software, and (2) offer you this License
  43 giving you legal permission to copy, distribute and/or modify it.
  44
  45   For the developers' and authors' protection, the GPL clearly explains
  46 that there is no warranty for this free software.  For both users' and
  47 authors' sake, the GPL requires that modified versions be marked as
  48 changed, so that their problems will not be attributed erroneously to
  49 authors of previous versions.
  50
  51   Some devices are designed to deny users access to install or run
  52 modified versions of the software inside them, although the manufacturer
  53 can do so.  This is fundamentally incompatible with the aim of
  54 protecting users' freedom to change the software.  The systematic
  55 pattern of such abuse occurs in the area of products for individuals to
  56 use, which is precisely where it is most unacceptable.  Therefore, we
  57 have designed this version of the GPL to prohibit the practice for those
  58 products.  If such problems arise substantially in other domains, we
  59 stand ready to extend this provision to those domains in future versions
  60 of the GPL, as needed to protect the freedom of users.
  61
  62   Finally, every program is threatened constantly by software patents.
  63 States should not allow patents to restrict development and use of
  64 software on general-purpose computers, but in those that do, we wish to
  65 avoid the special danger that patents applied to a free program could
  66 make it effectively proprietary.  To prevent this, the GPL assures that
  67 patents cannot be used to render the program non-free.
  68
  69   The precise terms and conditions for copying, distribution and
  70 modification follow.
