I use a few such scripts, for example:

source <(curl -s https://slackbuilds.org/slackbuilds/14.2/system/isdct/isdct.info | grep "VERSION\|HOMEPAGE")
cat /usr/doc/isdct-*/isdct.SlackBuild |grep "VERSION=\${VERSION:-$VERSION}" > /dev/null || exit 0
s=$(curl -s "$HOMEPAGE" | grep -c "Version:.*Latest")
[ $s -eq 1 ] && exit 0
>&2 echo "New version of isdct, see $HOMEPAGE"
s=$(ls /var/log/packages/krop* | grep -c $(curl -s http://arminstraub.com/software/krop | grep -A1000000 "Changelog" | grep -m1 -o "krop [0-9\.]*" | grep -m1 -o "[0-9\.]*"))
[ $s -eq 1 ] && exit 0
>&2 echo "New release of krop, see http://arminstraub.com/software/krop"

IMO, better to use cron.daily, because .weekly only delays the
information, not reduces the amount of job.

Fortunately, in case of sourceforge one can simply subscribe for
information on new releases, and in case of github there is rss (which
can be checked via rss2email).
