"""
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.
