61 (description
62 "The primary goal of this project is to define a portable and efficient C
63programming interface (API) to determine the call-chain of a program. The API
64additionally provides the means to manipulate the preserved (callee-saved)
65state of each call-frame and to resume execution at any point in the
66call-chain (non-local goto). The API supports both local (same-process) and
67remote (across-process) operation. As such, the API is useful in a number of
68applications.")
