# 05/03 Markus Spiekermann. Makefile revised to make it Windows/Unix
#    compatible. Automatic enumeration of pd files is now done by a
#    lex generated scanner, this is a replacement for the perl solution.
#
# 10/03 Markus Spiekermann. Target install introduced.
#
# 05/04 Markus Spiekermann. Changes in documentation and script files.
# 12/06 Markus Spiekermann. More generic rules introduced.
