# We now use a 3-pass build system.  This needs to be re-thought....
#
# Pass 1. export  - Create generated headers and stubs.  Publish public headers
#                   to dist/include.
#
# Pass 2. libs    - Create libraries.  Publish libraries to dist/lib.
#
# Pass 3. install - Create programs.  Publish them to dist/bin.
#
# 'gmake' will build each of these properly, but 'gmake -jN' will break (need
# to do each pass explicitly when using -j).
#
# Parameters to this makefile (set these before including):
#
# a)
#	TARGETS	-- the target to create
#			(defaults to $LIBRARY $PROGRAM)
# b)
#	DIRS	-- subdirectories for make to recurse on
#			(the 'all' rule builds $TARGETS $DIRS)
# c)
#	CSRCS, CPPSRCS -- .c and .cpp files to compile
#			(used to define $OBJS)
# d)
#	PROGRAM	-- the target program name to create from $OBJS
# d2)
#	SIMPLE_PROGRAMS	-- Compiles Foo.cpp Bar.cpp into Foo, Bar executables.
# e)
#	LIBRARY_NAME	-- the target library name to create from $OBJS
# f)
#	JSRCS	-- java source files to compile into class files
#			(if you don't specify this it will default to *.java)
# g)
#	PACKAGE	-- the package to put the .class files into
#			(e.g. netscape/applet)
# h)
#	JMC_EXPORT -- java files to be exported for use by JMC_GEN
#			(this is a list of Class names)
# i)
#	JRI_GEN	-- files to run through javah to generate headers and stubs
#			(output goes into the _jri sub-dir)
# j)
#	JNI_GEN	-- files to run through javah to generate headers and stubs
#			(output goes into the _jni sub-dir)
# k)
#	JMC_GEN	-- files to run through jmc to generate headers and stubs
#			(output goes into the _jmc sub-dir)
