   3 # Use this script to profile cvs2svn.py using Python's hotshot profiler.
   4 #
   5 # The profile data is stored in cvs2svn.hotshot.  To view the data using
   6 # hotshot, run the following in python:
   7 #
   8 #      import hotshot.stats
   9 #      stats = hotshot.stats.load('cvs2svn.hotshot')
  10 #      stats.strip_dirs()
  11 #      stats.sort_stats('time', 'calls')
  12 #      stats.print_stats(20)
  13 #
  14 # It is also possible (and a lot better) to use kcachegrind to view the data.
  15 # To do so, you must first convert the data to the cachegrind format using
  16 # hotshot2cachegrind, which you can download from the following URL:
  17 #
  18 # http://kcachegrind.sourceforge.net/cgi-bin/show.cgi/KcacheGrindContribPython
  19 #
  20 # Convert the data using the following command:
  21 #
  22 #      hotshot2cachegrind -o cachegrind.out cvs2svn.hotshot
  23 #
  24 # Depending on the size of the repository, this can take a long time. When
  25 # the conversion is done, simply open cachegrind.out in kcachegrind.
