%description
    This library provides a portable and efficient C programming
    interface (API) to determine the call-chain of a program. The
    API additionally provides the means to manipulate the preserved
    (callee-saved) state of each call-frame and to resume execution at
    any point in the call-chain (non-local goto). The API supports both
    local (same-process) and remote (across-process) operation.
