# 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:

# - Show body dialog when user does not choose any body files.

# - Save user input so that it can be played back in case of failure
# to send.

# - Set the size of all the dialogs to reasonable values. # - Reliable detection of failure 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.
