suggestion for ACD syntax

[Guy Bottu]

	Dear developpers,

Yesterday I had a discussion with Marc Colet, developper of the EMBOSS 
interface wEMBOSS and we have a suggestion for a small extension of the 
ACD syntax. It would be nice if the parameter type "infile" had an 
attribute "extension", so that the program would only accept input files 
with a name ending with ... This would perhaps not be so useful at the 
command line, but in a GUI this would allow for a selector with a filter 
showing only the appropriate files.

	Regards,
	Guy Bottu,
