+# Notes on building for AAS using Windows (7) + Visual Studio (2010) + Cygwin:
+#
+# Either this should be run indirectly from the VS command prompt via the
+# BuildICUForAAS script or project, using the instructions there (which build
+# both 32-bit and 64-bit), or it should be run from within Cygwin using the
+# following instructions or equivalent (different steps for 32-bit or 64-bit):
+#
+# 1. From VS command prompt, run vcvarsall.bat to set various environment variables.
+#    For a 32-bit build:
+#    > "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcvarsall.bat" x86
+#    For a 64-bit build:
+#    > "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcvarsall.bat" amd64
+#
+# 2. Launch Cygwin, e.g.
+#    > C:\cygwin\Cygwin.bat
+#
+# 3. Within cygwin, cd to the top level of the ICU sources directory, e.g.
+#    $ cd ICU
+#
+# 4. Adjust the PATH to put the appropriate VC tools directory first:
+#    For a 32-bit build:
+#    $ export PATH="/cygdrive/c/Program Files (x86)/Microsoft Visual Studio 10.0/VC/bin/":$PATH
+#    For a 64-bit build:
+#    $ export PATH="/cygdrive/c/Program Files (x86)/Microsoft Visual Studio 10.0/VC/bin/amd64/":$PATH
+#
+# 5. Run the ICU makefile
+#    For a 32-bit build:
+#    make [install] WINDOWS=YES [ARCH64=NO] [DSTROOT=...]
+#    For a 64-bit build:
+#    make [install] WINDOWS=YES ARCH64=YES [DSTROOT=...]
