+# KBUILD Makefile for the NVIDIA Linux kernel module.
+#
+# The motivation for replacing the original Makefile is the hope that this
+# version will simplify the build and installation process. In the past,
+# many architectural and cosmetic changes to the Linux kernel have made it
+# difficult to maintain compatibility or required duplication of logic.
+#
+# Linux 2.5 introduces numerous such changes, many of which impact modules.
+# Relying on KBUILD, some aspects of the build system otherwise difficult
+# to support (for example, module versioning) are abstracted away and dealt
+# with elsewhere, making life significantly easier here.
+#
+# The new approach currently has its own share of problems, some of which
+# are architectural difficulties with KBUILD, others minor annoyances. For
+# this reason, an improved version of the NVIDIA Makefile is available to
+# those experiencing difficulties.
