 [c++filt](https://www.gnu.org/software/binutils/ "GNU Binutils") is a demangling tool that converts mangled C++ symbols into human readable strings by calling `c++filt <symbol>`. See [the man page](https://ftp.gnu.org/old-gnu/Manuals/binutils-2.12/html_node/binutils_11.html "c++filt") for more information on its usage.
