I have a small shell script setup to check whenever I think about it:

### begin myschk.sh ###
#!/bin/bash
cd /home/pi/mystic
echo "Current version:"
/home/pi/mystic/mystic -ver
cd /tmp
[ -f "/tmp/mys112a47_p32.zip" ] && rm -f /tmp/mys112a47_p32.zip
wget -q http://mysticbbs.com/downloads/prealpha/mys112a47_p32.zip
echo #
unzip -l ./mys112a47_p32.zip
echo #
read -p "Delete zip? " -n 1 -r
echo #
if [[ $REPLY =~ ^[Yy]$ ]]
then
   rm -f /tmp/mys112a47_p32.zip
fi
echo #
### end myschk.sh ###


$ ./myschk.sh
