#
#==============================================================================#
# This file should be exactly the same in each section of the CVS.  A copy is
# kept in each section of the CVS so that each section will be self-contained.
# To use it, you need to include it in your Makefile (i.e. "include
# Makefile.buildlayout") and then define $(prefix) and $(cvs_root_dir).
#
# $(cvs_root_dir) is the base directory of src tree, equivalent to the root
# level of the pure-data CVS.
#
# $(prefix) is the base directory to where all of the resulting files
# will be copied.
#
# This file is currently located in these places: 
#	  abstractions
#	  externals
# 	  packages
#    doc
#
# it will be going here too:
#    gem
#    pd

# <hans@at.or.at>
