For example, if you go,
ftp://ftp.linux.cz/pub/localization
/OpenOffice.org/devel
/1.1.1/build-14/build/
and read,
build, build.functions, build.test,
you will learn how to build multiple localized ooo efficiently.
But it is difficult for an unwary semi-experienced serial ooo builder to read and understand them.
Notwithstanding, you can do it because they are all on the table.
They are fantastic!
