# Making a binary distribution
#
# To make a particular binary distribution: 
# 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'.
# 
#      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.
# 
#      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.
#
#	binary-dist is an FPtools addition for binary distributions
