+"""
+Support for converting linked targets to ihex, srec or binary files using
+objcopy. Use the 'objcopy' feature in conjunction with the 'cc' or 'cxx'
+feature. The 'objcopy' feature uses the following attributes:
+
+objcopy_bfdname		Target object format name (eg. ihex, srec, binary).
+					   Defaults to ihex.
+objcopy_target		 File name used for objcopy output. This defaults to the
+					   target name with objcopy_bfdname as extension.
+objcopy_install_path   Install path for objcopy_target file. Defaults to ${PREFIX}/fw.
+objcopy_flags		  Additional flags passed to objcopy.
