+    kage from the official binary (RPM\'s)\ndistributed by The Document Foundation.
+     Everything needed by the\napplication should be built statically into it, so th

+     to look at the script for some optional things you can do when\nbuilding.\n\nNO
+    TE: See the separate SlackBuild script for the language packs.\n\nNOTE2: To keep
+     LibreOffice installed concurrently with OpenOffice, run the\n       included "o
