[texhax] Information about document in the document

[Tom Backer Johnsen]

For some of the documents I write I would like to include a line in the 
upper left corner of the first page containing (a) the directory and 
name of the main file, and (b) the date and the time the document was 
printed.  At the same time I would like to drop the date that appears by 
default when using the \maketitle command.

I know about the \jobname command which gives the name of the main file 
(without the extension), but how do I get hold of the (full) directory 
path and the date/time?
