一个很不错的程序切片工具,希望大家来讨论以下,对测试人员很有帮助

                         Main Control Panel Help



                             Welcome to unravel

  Unravel is a software analysis tool for extracting source program
statements relevant to a computation.  The computation is defined as
the state of some program variable at some statement in the program.

  This is the main control window for unravel.  Before a slice can be
computed, the source files must be examined (analyzed) to build the
data structures needed to compute a program slice.

  The main panel has several buttons to invoke each part of unravel,
review results and ask to see this help file.  The main panel also
displays the analysis status of each source file in the current directory.

  A typical unravel session would require the following:
(1) Preparation -- Load the source files into a directory
(2) Run the unravel program -- This brings up the main control window
(3) Run the Analyzer -- Push the Run Analyzer button.  This brings up
the analyzer panel where the files to analyze are selected.  From the
analyzer panel, the button Analyze Selected Files will run the
analyzer on the selected files.  This builds data structures and
support files needed to perform slicing.  If any source does not
contain ANSI C unravel cannot analyze that file.  
(4) Review analysis results -- Examine the analysis results by pushing
the REVIEW HISTORY button and selecting Last Analysis from the menu.
This brings up the results of the last run of the analyzer.
(5) Run the Slicer  -- Push the Run Slicer button.  This brings up the
slicer panel.  From this panel you can calculate slices on the source
programs.
