+Usage: Do-compile-win [options] source-tarball
+
+Unpacks a Windows source distribution on the local machine and 
+compiles it using VC++ 6.0.
+
+This script is intended for Cygwin Perl. You must have a working 
+MSDEV.EXE in your path for compilation.
+
+
+Options:
+
+--help
+Print this text.
+
+--builddir=<dir>
+Set the Cygwin path to build under; the tarball will actually 
+be moved to <builddir>/mysql-<version>/tarball and extracted under 
+<builddir>/mysql-<version>/build.
+Default: /cygdrive/c/mysql-win-build
+
+--tarball=<file>
+Windows source tarball to use for this build. Must be of the form
+mysql[com]-x.x.x-win-src.tar.gz (REQUIRED)
+
+EOF
+	exit 1;
