+# SC - Compile Scala Files
+##############################################################################
+# $Id$
+
+##############################################################################
+# Usage
+#
+#   make sc [target=<target>] {<VARIABLE>=<value>}
+#
+##############################################################################
+# Variables
+#
+# SC_COMPILER		 = compiler name, for example SCALAC
+# $(SC_COMPILER)	 = compiler command
+# $(SC_COMPILER)_FLAGS	 = compiler-specific compilation flags
+# SC_FLAGS		+= compilation flags
+# SC_CLASSPATH		 = location of user class files
+# SC_SOURCEPATH		 = location of input source files
+# SC_BOOTCLASSPATH	 = location of bootstrap class files
+# SC_EXTDIRS		 = location of installed extensions
+# SC_OUTPUTDIR		 = directory where to place generated class files
+# SC_ENCODING		 = character encoding used by source files
+# SC_SOURCE		 = version of source code
+# SC_TARGET		 = version of target bytecode
+# SC_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 SC_CLASSPATH with target LIBRARY, one may define the
+# variable LIBRARY_SC_CLASSPATH
+#
+##############################################################################
+# Examples
+#
+# Compile file "sources/scala/Predef.scala"
+#
+#   make sc SC_FILES=sources/scala/Predef.scala
+#
+#
+# Compile the whole runtime
+#
+#   make sc target=LIBRARY
+#
+#
+# A Makefile rule that compiles all modified files from the runtime
+#
+#   .latest-library		: $(LIBRARY_SC_FILES)
+#           @$(MAKE) sc target=LIBRARY LIBRARY_SC_FILES='$?'
+#           touch $@
