# Version:
# 2012-03-04:
# - Temp file changed to /tmp/
#
# 2012-02-07:
# - PATH variable modified to include the bootstrap directory
#
# 2011-12-11:
# - Hibernation problem seems to be fixed now the tmp file is on /volume1
#
# 2011-12-10:
# - Git pull fixed
#
# 2011-12-03:
# - Git returned an error
#
# 2011-11-28:
# - Go to the spotweb directory to overcome missing files before the git pull is done
#
# 2011-11-26:
# - Logging removed to new file
#
# 2011-11-20:
# - Added some more variable to the script
# - Built-in check to see if git changed some files
