# Cross-platform Makefile generator.
#
# Reads the file `Recipe' to determine the list of generated
# executables and their component objects. Then reads the source
# files to compute #include dependencies. Finally, writes out the
# various target Makefiles.

# PuTTY specifics which could still do with removing:
#  - Mac makefile is not portabilised at all. Include directories
#    are hardwired, and also the libraries are fixed. This is
#    mainly because I was too scared to go anywhere near it.
#  - sbcsgen.pl is still run at startup.
#
# FIXME: no attempt made to handle !forceobj in the project files.
