Efforts/Package Restructuring/3rd Party Stuff
From Apache OpenOffice Wiki
OOo makes use of many 3rd party code. This 3rd party stuff needs to be separated, ideally into dedicated packages, in a way that it can be abandoned if needed / wished, e.g. to use platform provided versions.
The external stuff of OOo can be found on http://wiki.services.openoffice.org/wiki/External/Modules.
