// This header plugs in the leaks of string functions that are called as
// std::<function>. To plug these leaks we need to be able to strictly defined
// when <cstring> is included and redefine the desired functions afterwared.
// Additionally, unlike the other poems, we also need to define a function in
// the std namespace that forwards its call to the globally namespaced
// counterpart.
//
// *IMPORTANT*
// This header MUST be included at the top of the targeted file or we cannot
// guarantee when <cstring> will be included. The order of this include must be
// preserved or the leaks will not be plugged.
