# description: Sharity is a client for the Microsoft networking protocol CIFS.

# General Description:
# This script starts or stops the sharityd daemon. It is suitable to be
# called from a startup directory. For most systems it is sufficient to
# make a link from this file into the startup directory.
#
# Arguments:
#   start       start the daemon
#   stop        shutdown the daemon
#
# If called with no arguments, the daemon is started.

Dear System Administrator,
this is a mail from your Sharity software. The Sharity daemon has
crashed and dumped core, sorry about that. Please help us (Objective
Development) to find this bug! We need the core file, which has been
backed up to ${COREDIR}/core.backup
and we need your sharityd executable, which can be found at
${SERVER}. Please compress both files
into an archive and mail it to <[e-mail]>. Since core-files
and executables tend to be LARGE files, please get in contact with us
BEFORE you mail us the files; the bug may already be known or even fixed
in a newer release!

Security Note: core files may contain private data such as the content
of your files or your passwords. Please be aware of this fact when you
mail the core file.

Regards,
your Sharity software.
