# This is a script meant for RPM based systems.
#
# It verifies that the currently installed Nautilus
# RPM has the correct version of Bonobo installed.
#
# We will probably add more sanity checks here
# as we learn of specific problems that break the
# Nautilus RPM.
#

# This script is meant to be call by the script that
# launched Nautilus.  Currently that is run-nautilus.
#
# The result value of this script is:
#
# 0: Nautilus launch may continue.  This happens if
#    one of the following occured:
#
#    a.  No error was detected
#    b.  An unknown error was detected but the user
#        chose to continue.
#    c.  This is not an RPM based system.
#    d.  Either Bonobo or Nautilus RPMS were not
#        found in the system.  This is a special
#        case which occurs in debug builds.  
#        Lots of people use run-nautilus with
#        with debug builds, so we dont want to 
#        break that for them.  Its possible we
#        might handle this case differently in
#        the future.  For example, we could have
#        separate launch scripts for debug and 
#        rpm installations of Nautilus.
# 
# 1: Nautilus launch should be aborted.  An error
#    known to break Nautilus was detected.
