Update Snippet
(In lieu of deleting snippets, we would like to update a snippet,
so that we don't lose the relationships within which that snippet
is involved.  So when we do a snippet merge, instead of deleting
the original snippet, and then inserting a new "merged" snippet, 
we would like to update the old snippet in place.)



# ActionInterval
#  The interval (in seconds) between attempts by the program to
#  process data.  Processing of data has different meanings depending
#  on what mode the program is running in.  Default is 20.
# ActionInterval 20

# ProgramMode
#  The mode that the program is running in.  Supported modes are:
#  ALWAYS_CHECK_LIST
#   Each time the program "processes data" it connects to the database,
#   checks the list of snippets scheduled to be retrieved, and attempts
#   to retrieve the ones that are scheduled to be retrieved now.
#  ALWAYS_GET_SNIPPETS
#   Each time the program "processes data" it connects to the database,
#   and attempts to retrieve snippet data for each request in the database
#   regardless of whether it is scheduled to be retrieved or not.
#  STANDARD_DATA_MODE
#   Only connect to the database when the program knows that there 
#   are snippets currently scheduled for retrieval, or when the program
#   receives an ALERT or TRIGGER message via an Earthworm Ring.
#
#  The default mode is STANDARD_DATA_MODE
# ProgramMode  STANDARD_DATA_MODE
