delete buffers matching pattern

[Wim R. Crols]

Is there a way to delete all buffers matching a certain pattern?
For example, suppose I just read in all files in a directory and this is 
my buffer list:
1 "a.txt"
2 "b.txt"
3 "1.exe"
4 "2.exe"
5 "c.txt"
6 "3.exe"
7 "d.txt"
I want to do something like ":bdelete *.exe".
I don't want to manually enumerate all the buffer nummers like ":bdelete 
3 4 6"

Thanks,
Wim
