slackbuilds/office/libreoffice/README

LibreOffice is a productivity suite that is compatible with other major
office suites, and available on a variety of platforms. It is free
software and therefore free to download, use and distribute.

This script builds a Slackware package from the official binary (RPM's)
distributed by The Document Foundation.  Everything needed by the
application should be built statically into it, so there aren't any
dependencies not satisfied by a normal installation.

Be sure to look at the script for some optional things you can do when
building.

NOTE:
See the separate SlackBuild script for the language packs.
Avahi is only needed if you need to use Impress.
