-# set $(Project) to the name of the project, capitalised (eg. Ghc or Happy).
-
-# `dist' `binary-dist'
-#      Create a distribution tar file for this program. The tar file
-#      should be set up so that the file names in the tar file start with
-#      a subdirectory name which is the name of the package it is a
-#      distribution for. This name can include the version number.
-#
-#      For example, the distribution tar file of GCC version 1.40 unpacks
-#      into a subdirectory named `gcc-1.40'.
+# include inc1.mk
 # 
-#      The easiest way to do this is to create a subdirectory
-#      appropriately named, use ln or cp to install the proper files in
-#      it, and then tar that subdirectory.
+# inc1.mk : Makefile
+# 	echo "X = C" >$@
 # 
-#      The dist target should explicitly depend on all non-source files
-#      that are in the distribution, to make sure they are up to date in
-#      the distribution. See Making Releases.
