# Send an email to notify changes made in a directory of the NAS #

# TODO: #
# * option to set a minimum number of modifications before sending email #
# * rollback logging support #
# * demonize the script #
# * plain text connection with telnet (it shouldn't worth it) #
# #
# LIMITATIONS: #
# * this script is not intended to monitor a directory with waaaay too #
# much files inside it #
# * UTF8 and strange (but legal) ASCII email addresses may cause problems #
# * encoding of email message may be limited #
# #
# COMMENT: #
# * an implementation with "inotify" and "sendmail" is without a doubt a #
# much better approach, but DSM doesn't provide it by default #
