# 1- Deletes the last sdatxxxx.exe, dat-xxxx.zip
#    and update.ini files from the sources directory
# 2- grabs new sdatxxxx.exe, dat-xxxx.zip and update.ini
#    file from Network Associate ftp Site
# 3- saves new files in sources directory
# 4- copies the new files in the samba-shared autoupgrade
#    directory renaming sdatxxxx.exe as Setup.exe
#
# ToDo: check if file version has changed on the FTP directory
#       so we don't download if it is the same version as we
#       already have

# Included in crontab for Clavel this way
#
# /* this sets emacs as default editor */
# tcsh> setenv EDITOR /local/go/em
#
# /* this launches edition of the crontab file */
# tcsh> crontab -e
# /* edit only this way for cron to be aware */
# 
# em> 0 5 * * 0-6 $HOME/bin/getvirusdef > /dev/null
# save (C-x C-s) and quit (C-x C-c) emacs
#
# So that script runs every day at 05:00
# See "man crontab" for more details.

#
# WARNING : the default shell for cron is sh and
# the default path /usr/bin. So the path to programs
# anywhere else has to be explicit (e.i. /local/bin/wget)
#
# WARNING2 : in order to run this script
# you NEED wget version 1.7 minimum because ftp.nai.com runs
# on a Windows OS and there is a compatibility issue with
# older versions of Wget.
