    (synopsis "Determining the call chain of a program")
    (description
     "The primary goal of this project is to define 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.")
