+The standalone Windows installer for Mercurial is built in a somewhat
+jury-rigged fashion.
+
+It has the following prerequisites. Ensure to take the packages
+matching the mercurial version you want to build (32-bit or 64-bit).
+
+  Python 2.6 for Windows
+      http://www.python.org/download/releases/
+
+  A compiler:
+    either MinGW
+      http://www.mingw.org/
+    or Microsoft Visual C++ 2008 SP1 Express Edition
+      http://www.microsoft.com/express/Downloads/Download-2008.aspx
+
+  Python for Windows Extensions
+      http://sourceforge.net/projects/pywin32/
+
+  mfc71.dll (just download, don't install; not needed for Python 2.6)
+      http://starship.python.net/crew/mhammond/win32/
+
+  Visual C++ 2008 redistributable package (needed for >= Python 2.6 or if you compile with MSVC)
+    for 32-bit:
+      http://www.microsoft.com/downloads/details.aspx?FamilyID=9b2da534-3e03-4391-8a4d-074b9f2bc1bf
+    for 64-bit:
+      http://www.microsoft.com/downloads/details.aspx?familyid=bd2a6171-e2d6-4230-b809-9a8d7548c1b6
+
+  The py2exe distutils extension
+      http://sourceforge.net/projects/py2exe/
+
+  GnuWin32 gettext utility (if you want to build translations)
+      http://gnuwin32.sourceforge.net/packages/gettext.htm
+
+  Inno Setup
+      http://www.jrsoftware.org/isdl.php#qsp
+
+      Get and install ispack-5.3.10.exe or later (includes Inno Setup Processor),
+      which is necessary to package Mercurial.
+
+  ISTool - optional
+      http://www.istool.org/default.aspx/
+
+  add_path (you need only add_path.exe in the zip file)
+      http://www.barisione.org/apps.html#add_path
+
+  Docutils
+      http://docutils.sourceforge.net/
+
+  CA Certs file
+      http://curl.haxx.se/ca/cacert.pem
+
+And, of course, Mercurial itself.
+
+Once you have all this installed and built, clone a copy of the
+Mercurial repository you want to package, and name the repo
+C:\hg\hg-release.
+
+In a shell, build a standalone copy of the hg.exe program.
+
+Building instructions for MinGW:
+  python setup.py build -c mingw32
+  python setup.py py2exe -b 2
+Note: the previously suggested combined command of "python setup.py build -c
+mingw32 py2exe -b 2" doesn't work correctly anymore as it doesn't include the
+extensions in the mercurial subdirectory.
+If you want to create a file named setup.cfg with the contents:
+[build]
+compiler=mingw32
+you can skip the first build step.
+
+Building instructions with MSVC 2008 Express Edition:
+  for 32-bit:
+    "C:\Program Files\Microsoft Visual Studio 9.0\VC\vcvarsall.bat" x86
+    python setup.py py2exe -b 2
+  for 64-bit:
+    "C:\Program Files\Microsoft Visual Studio 9.0\VC\vcvarsall.bat" x86_amd64
+    python setup.py py2exe -b 3
+
+Copy add_path.exe and cacert.pem files into the dist directory that just got created.
+
+If you are using Python 2.6 or later, or if you are using MSVC 2008 to compile
+mercurial, you must include the C runtime libraries in the installer. To do so,
+install the Visual C++ 2008 redistributable package. Then in your windows\winsxs
+folder, locate the folder containing the dlls version 9.0.21022.8.
+For x86, it should be named like x86_Microsoft.VC90.CRT_(...)_9.0.21022.8(...).
+For x64, it should be named like amd64_Microsoft.VC90.CRT_(...)_9.0.21022.8(...).
+Copy the files named msvcm90.dll, msvcp90.dll and msvcr90.dll into the dist
+directory.
+Then in the windows\winsxs\manifests folder, locate the corresponding manifest
+file (x86_Microsoft.VC90.CRT_(...)_9.0.21022.8(...).manifest for x86,
+amd64_Microsoft.VC90.CRT_(...)_9.0.21022.8(...).manifest for x64), copy it in the
+dist directory and rename it to Microsoft.VC90.CRT.manifest.
+
+Before building the installer, you have to build Mercurial HTML documentation
+(or fix mercurial.iss to not reference the doc directory):
+
+  cd doc
+  mingw32-make html
+  cd ..
+
+If you use ISTool, you open the
+C:\hg\hg-release\contrib\packaging\inno\mercurial.iss
+file and type Ctrl-F9 to compile the installer file.
+
+Otherwise you run the Inno Setup compiler.  Assuming it's in the path
+you should execute:
+
+  iscc contrib\packaging\inno\mercurial.iss /dVERSION=foo
+
+Where 'foo' is the version number you would like to see in the
+'Add/Remove Applications' tool.  The installer will be placed into
+a directory named Output/ at the root of your repository.
+If the /dVERSION=foo parameter is not given in the command line, the
+installer will retrieve the version information from the __version__.py file.
+
+If you want to build an installer for a 64-bit mercurial, add /dARCH=x64 to
+your command line:
+  iscc contrib\packaging\inno\mercurial.iss /dARCH=x64
+
+To automate the steps above you may want to create a batchfile based on the
+following (MinGW build chain):
+
+  echo [build] > setup.cfg
+  echo compiler=mingw32 >> setup.cfg
+  python setup.py py2exe -b 2
+  cd doc
+  mingw32-make html
+  cd ..
+  iscc contrib\packaging\inno\mercurial.iss /dVERSION=snapshot
+
+and run it from the root of the hg repository (c:\hg\hg-release).
