# Purpose: a script intended to be executed from file managers such as
# Nautilus to send files to a Posterous blog.
# Dependencies:
# Zenity
# sendEmail # Perl, # Net::SSLeay and IO::Socket::SSL perl modules
# Description: # This script accepts a number of file names as arguments and expects
# a configuration file to exist in a directory called
# .sendtoposterous in the user's home directory. 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.
# The .sendtoposterous directory is also used to maintain a history of
# post titles and tags as well as temporary files associated with
# building the email message.
#====================================================
# 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.

# Revision 1.10 2011/05/02 19:33:05 kj
# Fixed tags file so that only the tags need to be present. Uses sed to add boolean False before each line.
#
# Revision 1.9 2011/05/02 19:21:37 kj
# Tags history now works.
#
# Revision 1.8 2011/05/02 17:52:00 kj
# Added title history and tags.
#
# Revision 1.7 2011/04/29 16:12:12 kj
# Changed from a single config file to a config directory so that we can store history.
#
# Revision 1.6 2011/04/27 20:41:40 kj
# Added post title as text on progress dialog.
#
# Revision 1.5 2011/04/27 19:41:51 kj
# Removed grep filtering of progress, pulsating bar works now.
#
# Revision 1.4 2011/04/27 19:36:26 kj
