// AddHooks installs a global set of Wrappers which are applied to every error processed
// by this package. They are applied before any other Wrappers or stack capturing are
// applied. Hooks can add additional wrappers to errors, or translate annotations added
// by other error libraries into merry annotations.
//
// Note that these hooks will be applied each time an err is passed to Wrap/Apply. If you
// only want your hook to run once per error, see AddOnceHooks.
//
// This function is not thread safe, and should only be called very early in program
// initialization.

// AddOnceHooks is like AddHooks, but these hooks will only be applied once per error.
// Once hooks are applied to an error, the error is marked, and future Wrap/Apply calls
// on the error will not apply these hooks again.
//
// This function is not thread safe, and should only be called very early in program
// initialization.
