I think this is close to being a FAQ.  The last time it came up,
I think we settled on:


Looking at abspath() in the module index, it says on most platforms
it is equivalent to os.path.normpath(os.path.join(os.getcwd(), <<path>>))
If sys.argv[0] specifies an absolute path, that expression just
returns sys.argv[0].  If it is relative, it is converted to absolute
by joining with the current directory.
