 This module defines variables and macros required to build eCos application.
 
 This file contains the following macros:
-ECOS_ADD_INCLUDE_DIRECTORIES() - add the eCos include dirs
-ECOS_ADD_EXECUTABLE(name source1 ...  sourceN ) - create an eCos
-executable ECOS_ADJUST_DIRECTORY(VAR source1 ...  sourceN ) - adjusts
-the path of the source files and puts the result into VAR
-
-Macros for selecting the toolchain: ECOS_USE_ARM_ELF_TOOLS() - enable
-the ARM ELF toolchain for the directory where it is called
-ECOS_USE_I386_ELF_TOOLS() - enable the i386 ELF toolchain for the
-directory where it is called ECOS_USE_PPC_EABI_TOOLS() - enable the
-PowerPC toolchain for the directory where it is called
-
-It contains the following variables: ECOS_DEFINITIONS
-ECOSCONFIG_EXECUTABLE ECOS_CONFIG_FILE - defaults to ecos.ecc, if your
-eCos configuration file has a different name, adjust this variable for
-internal use only:
