# This is an example of a service hosted by python.exe rather than 
# pythonservice.exe.

# Note that it is very rare that using python.exe is a better option
# than the default pythonservice.exe - the latter has better error handling
# so that if Python itself can't be initialized or there are very early
# import errors, you will get error details written to the event log.  When
# using python.exe instead, you are forced to wait for the interpreter startup
# and imports to succeed before you are able to effectively setup your own
# error handling.

# So in short, please make sure you *really* want to do this, otherwise just
# stick with the default.
