+# From http://www.mingw.org/MinGWiki/index.php/BuildMingwCross
+#
+
+# This is my script for building a complete MinGW cross-compiler toolchain
+# that runs under Linux to produce executables that run under Windows.  It
+# probably works (or can easily be adapted to work) under any unix system.
+#
+# It is based in large part on Sam Lantinga's script, which in turn was
+# based partly on Ray Kelm's script, which in turn was built on
+# Mo Dejong's script for doing the same, but with some added fixes.
+#
+# My changes:
+#       1. Adapted the script to the new packaging of MinGW GCC, which is
+#          currently split into core and auxiliary components.
+#       2. The script now determines the GCC and BINUTILS directory name
+#          directly from the tar file contents.  This gets around common
+#          problems due to the directory names not always following the
+#          expected patterns.
+#       3. Grouped together and simplified the macros that users need to
+#          define.
+#       4. Made optional components truly optional -- leave the
+#          corresponding archive names blank and they will be ignored.
+#       5. Included an option to purge the installation directory before
+#          installing the current cross-compiler.
+#
+# NOTE: If you choose a destination directory for the installation (set
+# in the macro PREFIX) for which you do not have write access, you will
+# need to run this script with root (or equivalent) privileges.
