Unoconv Installation.

"unoconv" is a command line program that is used to convert between different office document file formats. It uses an instance of LibreOffice to do the conversion 

The steps required to install unoconv are different depending on the operating system that you have installed Moodle on. 

CentOS / RedHat

Just before you start, you might like to consider installing the latest LibreOffice. Before installing, please remove any openoffice packages you might have on your OS by issuing:

yum remove openoffice* libreoffice*

And then follow the install instructions LibreOffice 5.2. It is recommended to chose your localized libreoffice version for better document conversions.

Then, 

git clone https://github.com/dagwieers/unoconv.git # copy cp unoconv/unoconv /usr/bin # or link unoconv to /usr/bin ln -s unoconv/unoconv /usr/bin/unoconv
