# \param[out] 3 the debug symbols
# \param[out] 4 (optional)a copy of \p 1
# \note This is a convenience function for creating various binary files from
# the compiler executable output. The two types of files, the stripped
# executable and the debug symbol, should be kept for each release in order to
# analyse core dumps.
# \note When \p 4 is used, the function copies \p 1 to \p 4 and
# dumps the output of readelf to \c $READELF_PATH.
