# This is a little interactive tool which helps you
# to maintain your accounts on one place.

# It uses an encrypted database for protecting the
# account list. The tool does not work with temporary
# files for security reasons.
#
# Just execute it. It will show you a little menu of
# all available commands. That's really easy :-)
