    <title>Introduction to libunwind</title>

    <para>
      <application>libunwind</application> is 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. 
      As such, the API is useful in a number of applications.
