Several links are outdated

[scfc]

In the Perl cartridge template, several links now redirect to a generic https://docs.openshift.org/latest/welcome/index.html:

http://openshift.github.io/documentation/oo_cartridge_guide.html#perl
http://openshift.github.io/documentation/oo_user_guide.html#action-hooks
http://openshift.github.io/documentation/oo_user_guide.html#the-openshift-directory
https://docs.openshift.org/origin-m4/oo_cartridge_guide.html#cron
https://docs.openshift.org/origin-m4/oo_cartridge_guide.html#markers-6
https://docs.openshift.org/origin-m4/oo_user_guide.html#using-cartridges

I assume the same/similar links are used elsewhere, so other cartridges (or repositories) may be affected as well.
