This means that

- if you do not include the extension, and if you have made some  
change to fname.eps, you whall have to throw to the basket, manually,  

- if you include the extension, the .eps file will be reprocessed  
into pdf at every run.

A better behaviour would be to test if some .eps file has already  
processed into pdf or not, since it last revision. This requires  
maintaining some table in a separate file, but it would be very  
useful by saving much time of waiting in front of the screen.
