[horde] installing skeleton

[Barry O'shaughnessy]

I'm new to using Horde, only having just managed to get it installed
recently via a lengthy tutorial
(
https://www.howtoforge.com/tutorial/install-horde-5-webmail-for-ispconfig-on-debian-jessie/
)
only to find out I could have done an apt-get in Ubuntu or OpenSuse.

I would like to develop a new module and found the instructions to install
Skeleton
(as part of the docs/INSTALL file) but am unable to get it installed, I get
an "is not activated"
error message when I go to the page horde/skeleton can someone point me in
the right direction.

I can not see the module in the configuration page so cannot configure it
as per instructions.

Horde 5.2.22 Centos 6.4
