sigit 0.3.2-2 (armel binary) in ubuntu oneiric

 This small utility changes signatures in random order.
 It is compatible with all email and news
 clients that use $HOME/.signature although the
 signature file can be called anything. It works over
 NFS and can even handle multiple signature files.
 .
 The utility to manipulate signature databases,
 sigitdb, is also included.
