Ok, then "package directory" is wrong, but just "package and project" 
(as in the example below) is right.
"The IDE has one set of search paths for every package and project. That 
means a package can have different search paths than the active project. "

And imho better than "directory". Especially, since you just explained 
that directory stands for the set of directories of the package (or 
project).

Unless the sentence is supposed to mean:
each "directory" (as in truly one directory on the medium) is included 
in one (and just one) "search path" (a set of dirs), therefore there is 
one search path for each dir.

The term set of "search path" should then also be explained on the wiki, 
the same as in the above quote.

The term directory in that sentence is still misleading/ambiguous

I thought they are stored in the project/pacckage options? Only they get 
updated (if the user confirms) when files are added, removed, moved?
