Returns a dictionary with information about the running top level Python
script:
---------------------------------------------------------------------------
dir: directory containing script or compiled executable
name: name of script or executable
source: name of source code file

"name" and "source" are identical if and only if running interpreted code.
When running code compiled by py2exe or cx_freeze, "source" contains
the name of the originating Python script.
If compiled by PyInstaller, "source" contains no meaningful information.
