-  When we speak of free software, we are referring to freedom of use,

+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if
+you distribute copies of the library, or if you modify it.
 
   For example, if you distribute copies of the library, whether gratis
 or for a fee, you must give the recipients all the rights that we gave
 you.  You must make sure that they, too, receive or can get the source
-code.  If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
+code.  If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
 it.  And you must show them these terms so they know their rights.
 
-  We protect your rights with a two-step method: (1) we copyright the

+  Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
 permission to copy, distribute and/or modify the library.
 
-  To protect each distributor, we want to make it very clear that
-there is no warranty for the free library.  Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be

+  Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library.  If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, so that any problems introduced by others will not reflect on
+the original authors' reputations.
 
-  Finally, software patents pose a constant threat to the existence of
-any free program.  We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder.  Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software.  To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
 
-  Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License.  This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License.  We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
+  Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License, which was designed for utility programs.  This
+license, the GNU Library General Public License, applies to certain
+designated libraries.  This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
 
-  When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library.  The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom.  The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
+  The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it.  Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program.  However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
 
-  We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License.  It also provides other free software developers Less
-of an advantage over competing non-free programs.  These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries.  However, the Lesser license provides advantages in certain
-special circumstances.
+  Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries.  We
+concluded that weaker conditions might promote sharing better.
 
-  For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard.  To achieve this, non-free programs must be
-allowed to use the library.  A more frequent case is that a free
-library does the same job as widely used non-free libraries.  In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-  In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software.  For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-  Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
+  However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves.  This Library General Public License is intended to
+permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them.  (We have not seen how to achieve
+this as regards changes in header files, but we have achieved it as regards
+changes in the actual functions of the Library.)  The hope is that this
+will lead to faster development of free libraries.
 
   The precise terms and conditions for copying, distribution and
 modification follow.  Pay close attention to the difference between a
 "work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
+former contains code derived from the library, while the latter only
+works together with the library.
+
+  Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.

-Installation
-============
+LVM2 installation
+=================
 
-1) Generate custom makefiles.
+1) Install device-mapper
+
+   Ensure the device-mapper has been installed on the machine.
+
+   The device-mapper should be in the kernel (look for 'device-mapper'
+   messages in the kernel logs) and /usr/include/libdevmapper.h 
+   and libdevmapper.so should be present.
+
+   The device-mapper is available from:
+     ftp://ftp.sistina.com/pub/LVM2/device-mapper/
+
+
+2) Generate custom makefiles.
 
    Run the 'configure' script from the top directory.
 
+   If you wish to use the built-in LVM2 shell and have GNU readline 
+   installed (http://www.gnu.org/directory/readline.html) use:
+     ./configure --enable-readline
+
    If you don't want to include the LVM1 backwards-compatibility code use:
      ./configure --with-lvm1=none 
 
    To separate the LVM1 support into a shared library loaded by lvm.conf use:
      ./configure --with-lvm1=shared
 
-   Use ./configure --help to see other options.
 
-2) Build and install.
+3) Build and install LVM2.
 
-   Run 'make' from the top directory to build everything you configured.
-   Run 'make install' to build and install everything you configured.
+   Run 'make install' from the top directory.
 
-   If you only want the device-mapper libraries and tools use
-   'make device-mapper' or 'make install_device-mapper'.
 
-3) If using LVM2, create a configuration file.
+4) Create a configuration file
 
    The tools will work fine without a configuration file being
    present, but you ought to review the example file in doc/example.conf.
+   For example, specifying the devices that LVM2 is to use can
+   make the tools run more efficiently - and avoid scanning /dev/cdrom!
 
 Please also refer to the WHATS_NEW file and the manual pages for the 
 individual commands.

-LVM2 Test Suite
-===============
-
-The codebase contains many tests in the test subdirectory.
-
-Before running tests
---------------------
-
-Keep in mind the testsuite MUST run under root user.
-
-It is recommended not to use LVM on the test machine, especially when running
-tests with udev (`make check_system`.)
-
-You MUST disable (or mask) any LVM daemons:
-
-- lvmetad
-- dmeventd
-- lvmpolld
-- lvmdbusd
-- lvmlockd
-- clvmd
-- cmirrord
-
-Some lvm.conf options should be set:
-
-- global/event_activation = 0
-- activation/monitoring = 0
-
-For running cluster tests, we are using singlenode locking. Pass
-`--with-clvmd=singlenode` to configure.
-
-NOTE: This is useful only for testing, and should not be used in production
-code.
-
-To run D-Bus daemon tests, existing D-Bus session is required.
-
-Running tests
--------------
-
-As root run:
-
-    make check
-
-To run only tests matching a string:
-
-    make check T=test
-
-To skip tests matching a string:
-
-    make check S=test
-
-There are other targets and many environment variables can be used to tweak the
-testsuite - for full list and description run `make -C test help`.
-
-Installing testsuite
---------------------
-
-It is possible to install and run a testsuite against installed LVM. Run the
-following:
-
-    make -C test install
-
-Then lvm2-testsuite binary can be executed to test installed binaries.
-
-See `lvm2-testsuite --help` for options. The same environment variables can be
-used as with `make check`.

-# SYNOPSIS
-#
-#   AX_GCC_BUILTIN(BUILTIN)
-#
-# DESCRIPTION
-#
-#   This macro checks if the compiler supports one of GCC's built-in
-#   functions; many other compilers also provide those same built-ins.
-#
-#   The BUILTIN parameter is the name of the built-in function.
-#
-#   If BUILTIN is supported define HAVE_<BUILTIN>. Keep in mind that since
-#   builtins usually start with two underscores they will be copied over
-#   into the HAVE_<BUILTIN> definition (e.g. HAVE___BUILTIN_EXPECT for
-#   __builtin_expect()).
-#
-#   The macro caches its result in the ax_cv_have_<BUILTIN> variable (e.g.
-#   ax_cv_have___builtin_expect).
-#
-#   The macro currently supports the following built-in functions:
-#
-#    __builtin_assume_aligned
-#    __builtin_bswap16
-#    __builtin_bswap32
-#    __builtin_bswap64
-#    __builtin_choose_expr
-#    __builtin___clear_cache
-#    __builtin_clrsb

-#    __builtin_prefetch
-#    __builtin_trap
-#    __builtin_types_compatible_p
-#    __builtin_unreachable
-#
-#   Unsuppored built-ins will be tested with an empty parameter set and the
-#   result of the check might be wrong or meaningless so use with care.

-# AM_PATH_PYTHON([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
-# ---------------------------------------------------------------------------
-# Adds support for distributing Python modules and packages.  To
-# install modules, copy them to $(pythondir), using the python_PYTHON
-# automake variable.  To install a package with the same name as the
-# automake package, install to $(pkgpythondir), or use the
-# pkgpython_PYTHON automake variable.
-#
-# The variables $(pyexecdir) and $(pkgpyexecdir) are provided as
-# locations to install python extension modules (shared libraries).
-# Another macro is required to find the appropriate flags to compile
-# extension modules.
-#
-# If your package is configured with a different prefix to python,
-# users will have to add the install directory to the PYTHONPATH
-# environment variable, or create a .pth file (see the python
-# documentation for details).
-#
-# If the MINIMUM-VERSION argument is passed, AM_PATH_PYTHON will
-# cause an error if the version of python installed on the system
-# doesn't meet the requirement.  MINIMUM-VERSION should consist of
-# numbers and dots only.

-Usage: py-compile [options] FILES...
-
-Byte compile some python scripts FILES.  Use --destdir to specify any
-leading directory path to the FILES that you don't want to include in the
-byte compiled file.  Specify --basedir for any additional path information you
-do want to be shown in the byte compiled file.
-
-Options:
-  --basedir DIR   Prefix all FILES with DIR, and include in error messages.
-  --destdir DIR   Prefix all FILES with DIR before compiling.
-  -v, --version   Display version information.
-  -h, --help      This help screen.
-
-Example:
-  py-compile --destdir /tmp/pkg-root --basedir /usr/share/test test.py test2.py
