# CSC - Compile C# Files

# $Id$

##############################################################################
# Usage
#
#   make csc [target=<target>] {<VARIABLE>=<value>}
#
##############################################################################
# Variables
#
# CSC_COMPILER		 = compiler name, for example CSC
# $(CSC_COMPILER)	 = compiler command
# $(CSC_COMPILER)_FLAGS	 = compiler-specific compilation flags
# CSC_FLAGS		+= compilation flags
# CSC_OUTPUTFILE	 = name of the generated assembly file
# CSC_REFERENCE		 = list of referenced assenblies
# CSC_ENCODING		 = character encoding used by source files
# CSC_SOURCE		 = version of source code
# CSC_TARGET		 = compilation target (exe, winexe, library, module)
# CSC_DEFINE		 = defines the symbols listed by the semicolon
#                          separated list
# CSC_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/AnyVal.cs"
#
#   make csc CSC_FILES=sources/scala/AnyVal.cs
#
#
# Compile the whole runtime
#
#   make csc target=LIBRARY
#
#
# A Makefile rule that compiles all modified files from the runtime
#
#   .latest-library		: $(LIBRARY_CSC_FILES)
#           @$(MAKE) csc target=LIBRARY LIBRARY_CSC_FILES='$?'
