# @FUNCTION: __save_ebuild_env
# @DESCRIPTION:
# echo the current environment to stdout, filtering out redundant info.
#
# --exclude-init-phases causes pkg_nofetch and src_* phase functions to
# be excluded from the output. These function are not needed for installation
# or removal of the packages, and can therefore be safely excluded.
