Actually, it means directory - any directory.
A package can have source files in many directories.
The search paths of a package are used for all files in all directories of a
package.
Same for projects.
The IDE has one set of search paths (unit search path, include search path,
sources search path) for each directory. It creates these sets on demand.
Whenever a file is parsed the IDE looks up its cache. If this is the first time
that a file in that directory is parsed, the IDE collects all settings and
calculates the search paths and compiler options. This data is not stored on
disk.

That is true too. If you think that is less confusing please change it.
