# RMIC - Generate Stubs for Java Class Files
##############################################################################
# $Id$
##############################################################################
# Usage
#
# make rmic [target=<target>] {<VARIABLE>=<value>}
#
##############################################################################
# Variables
#
# RMIC_COMPILER = compiler name, for example RMIC
# $(RMIC_COMPILER) = compiler command
# $(RMIC_COMPILER)_FLAGS = compiler-specific compilation flags
# RMIC_FLAGS += compilation flags
# RMIC_CLASSPATH = location of user class files
# RMIC_BOOTCLASSPATH = location of bootstrap class files
# RMIC_EXTDIRS = location of installed extensions
# RMIC_OUTPUTDIR = directory where to place generated class files
# RMIC_CLASSES += files to compile
#
# All variables may have target specific values which override the
# normal value. Those values are specified by variables whose name is
# prefixed with the target name. For example, to override the value of
# the variable RMIC_CLASSPATH with target COMPILER, one may define the
# variable COMPILER_RMIC_CLASSPATH.
#
##############################################################################
# Examples
#
# Compile file "objects/main/lib/scala/scala/runtime/distributed/ChannelImpl"
#
# make rmic RMIC_CLASSES=objects/main/lib/scala/scala/runtime/distributed/ChannelImpl
#
#
# Compile the whole runtime
#
# make rmic target=RUNTIME
#
#
# A Makefile rule that compiles all modified files from the runtime
#
# .latest-runtime : $(RUNTIME_RMIC_CLASSES)
# @$(MAKE) rmic target=RUNTIME RUNTIME_RMIC_CLASSES='$?'
# touch $@
