I've been there too :) In fact I am still there :)

That line is specifically for the Make file to grep in and find that it
should include the file in the build directory.

DBOBJECTS is a define()'d constant it is basically pointing to the
directory where bc_logged_in.inc is located.

see prepend.inc for the definition of import

They are trying to mimic the Java import statement using . instead of /
so they created a function called import() and it replaces the . into /
to include the file. Once you understand this construct you'll now how
to import() whatever file in BC that you want.

It's a shortcut of include_once really with a bit of help to translate
the correct path.
