    <title>Introduction to libunwind</title>

    <para>
      The <application>libunwind</application> package contains 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.
