# This is a helper for the win32trace module
# If imported from a normal Python program, it sets up sys.stdout and sys.stderr
# so output goes to the collector.
# If run from the command line, it creates a collector loop.
# Eg:
# C:>start win32traceutil.py (or python.exe win32traceutil.py)
# will start a process with a (pretty much) blank screen.
#
# then, switch to a DOS prompt, and type:
# C:>python.exe
# Python 1.4 etc...
# >>> import win32traceutil
# Redirecting output to win32trace remote collector
# >>> print "Hello"
# >>>
# And the output will appear in the first collector process.
# Note - the client or the collector can be started first.
# There is a 0x20000 byte buffer. If this gets full, it is reset, and new
# output appended from the start.
