#
# How to use:
#
# This script should be run after the release is complete. Meant for d1's
# Project-ZS v0.6.x, edit the following in zsconfig.h:
#
# #define enable_complete_script  TRUE
# #define complete_script         "/bin/nfoextract.sh"
#
# Then deny *.nfo uploads in your 0day dirs. Here is an example with the
# default precheck.sh (replace 0DAY with the name of your 0day dir):
#
#  *.[nN][fF][oO])
#   if [ ! "`echo $2 | grep 0DAY`" = "" ]; then
#    echo -e ".---=== GetNFO v0.5b =====--- psxc (C)2004 --====--.\n| NFO file uploads denied.                         |\n| The .nfo will instead be extracted from the zip. |\n\`--------=======-----------------=====-------------'\n"
#    exit 2
#   fi
#  ;;
#
# copy nfoextract.sh to glftpd's bin directory (/glftpd/bin) and make sure you have the following
# in glftpd's bin directory: bash chmod chown unzip ls echo cat
