# SDC - Compile Scala Documentation Files
##############################################################################
# $Id$
##############################################################################
# Usage
#
# make sdc [target=<target>] {<VARIABLE>=<value>}
#
##############################################################################
# Variables
#
# SDC_COMPILER = compiler name, for example SCALADOC
# $(SDC_COMPILER) = compiler command
# $(SDC_COMPILER)_FLAGS = compiler-specific compilation flags
# SDC_FLAGS += compilation flags
# SDC_CLASSPATH = location of user class files
# SDC_SOURCEPATH = location of input source files
# SDC_BOOTCLASSPATH = location of bootstrap class files
# SDC_EXTDIRS = location of installed extensions
# SDC_OUTPUTDIR = directory where to place generated class files
# SDC_ENCODING = character encoding used by source files
# SDC_SOURCE = version of source code
# SDC_TARGET = version of target bytecode
# SDC_FILES += 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 SDC_CLASSPATH with target LIBRARY, one may define the
# variable LIBRARY_SDC_CLASSPATH.
#
##############################################################################
# Examples
#
# Compile file "sources/scala/Predef.scala"
#
# make sdc SDC_FILES=sources/scala/Predef.scala
#
#
# Compile the whole runtime
#
# make sdc target=LIBRARY
#
#
# A Makefile rule that compiles all modified files from the runtime
#
# .latest-library : $(LIBRARY_SDC_FILES)
# @$(MAKE) sdc target=LIBRARY LIBRARY_SDC_FILES='$?'
# touch $@
