+XZ Utils for Windows
+====================
+
+Introduction
+------------
+
+    This package includes command line tools (xz.exe and a few others)
+    and the liblzma compression library from XZ Utils. You can find the
+    latest version and full source code from <http://tukaani.org/xz/>.
+
+    The parts of the XZ Utils source code, that are relevant to this
+    binary package, are in the public domain. XZ Utils have been built
+    for this package with MinGW and linked statically against the MinGW
+    runtime and w32api packages.
+
+    FIXME: Add license info about MinGW runtime and w32api.
+
+
+Package contents
+----------------
+
+    All executables and libraries in this package require msvcrt.dll.
+    It's included in all recent Windows versions. On Windows 95 it
+    might be missing, but once you get it somewhere, XZ Utils should
+    run even on Windows 95.
+
+    There are two different versions of the executable and library files.
+    There is one directory for each type of binaries:
+
+        bin_i486        32-bit x86 (i486 and up), Windows 95 and later
+        bin_x86-64      64-bit x86-64, Windows XP and later
+
+    Each of the above directories have the following files:
+
+        *.exe       Command line tools. (It's useless to double-click
+                    these; use the command prompt instead.) These have
+                    been linked statically against liblzma, so they
+                    don't require liblzma.dll. Thus, you can copy e.g.
+                    xz.exe to a directory that is in PATH without copying
+                    any other files from this package.
+
+        liblzma.dll Shared version of the liblzma compression library.
+                    This file is mostly useful to developers, although
+                    some non-developers might use it to upgrade their
+                    copy of liblzma.
+
+        liblzma.a   Static version of the liblzma compression library.
+                    This file is useful only for developers.
+
+    The rest of the directories contain architecture-independent files:
+
+        doc         Documentation in the plain text (TXT) format. The
+                    manuals of the command line tools are provided also
+                    in the PDF format. liblzma.def is in this directory
+                    too.
+
+        include     C header files for liblzma. These should be
+                    compatible with most C and C++ compilers. If you
+                    have problems, try to fix it and send your fixes
+                    upstream, or at least report a bug, thanks.

+
+Linking against liblzma
+-----------------------
+
+MinGW
+
+    If you use MinGW, linking against liblzma.dll or liblzma.a should
+    be straightforward. You don't need an import library to link
+    against liblzma.dll, and for static linking, you don't need to
+    worry about the LZMA_API_STATIC macro.
+
+    Note that the MinGW distribution includes liblzma. If you are
+    building packages that will be part of the MinGW distribution, you
+    probably should use the version of liblzma shipped in MinGW instead
+    of this package.
+
+
+Microsoft Visual C++
+
+    To link against liblzma.dll, you need to create an import library
+    first. You need the "lib" command from MSVC and liblzma.def from
+    the "doc" directory of this package. Here is the command that works
+    on 32-bit x86:
+
+        lib /def:liblzma.def /out:liblzma.lib /machine:ix86
+
+    On x86-64, the /machine argument has to naturally be changed:
+
+        lib /def:liblzma.def /out:liblzma.lib /machine:x64
+
+    Linking against static liblzma should work too. Rename liblzma.a
+    to e.g. liblzma_static.lib and tell MSVC to link against it. You
+    also need to tell lzma.h to not use __declspec(dllimport) by defining
+    the macro LZMA_API_STATIC. You can do it either in the C/C++ code
+
+        #define LZMA_API_STATIC
+        #include <lzma.h>
+
+    or by adding it to compiler options.
+
+
+Other compilers
+
+    If you are using some other compiler, see its documentation how to
+    create an import library (if it is needed). If it is simple, I
+    might consider including the instructions here.
