If the configuration file does not exist then#  Zenity is used to ask the user for the SMTP server name, user name,#  password and recipient name (preset to post@posterous.com but#  presumably others could implement a similar blog submission#  process).   #  Once the configuration data has been collected from the user it is#  saved and the user will not be asked again unless the#  -c/--configure option is given on the command line.#====================================================# To do:# - Reliable detection of filure to send.# - Use file as body.  Use file command to discover text files,#   present list so user can pick one to use as the body. #====================================================#         $Id: sendtoposterous,v 1.10 2011/05/02 19:33:05 kj Exp $        ## $Log: sendtoposterous,v $# Revision 1.10  2011/05/02 19:33:05  kj# Fixed tags file so that only the tags need to be present.
