+# So we sed off $(TOP). Unfortunately, on Windows, the case for the
+# drive letter is sometimes different in what $(TOP) starts with, and
+# what the path in the package database starts with. We therefore
+# need to do the substitution case-insensitively on Windows. But
+# the s///i modifier isn't portable, so we set CASE_INSENSITIVE_SED
+# to "i" on Windows and "" on any other platform.
