# This makefile is meant to parse with both normal `make' and `nmake'
# (on Windows). On Windows, prefix each target with `win32-'.

# The targets here do not use dependencies (mostly), so it's a strange
# use of `make'.  Really, this makefile is an alternative to a pile of
# scripts, where each target plays the role of a script.

# The main targets are
#
#  in-place = build in "racket" with all packages in development mode
#
#  core = build in "racket" only (i.e., first step of `in-place')
#
#  server = build core, build packages listed in $(PKGS), start 
#           server at port 9440
#
#  client = build core, create an installer with $(PKGS) with the help
#           of $(SERVER); result is recorded in "bundle/installer.txt"
