editing sieve scripts via command line

[Sunny]

Hi,

I would like to implement a script that sysadmin's can run to edit a 
users sieve script i.e. set out office or forward mail.
If the sieve script gets edited via command line (i.e. using vi) the 
changes are not seen in GUI and the changes doesn't take effect so I'm 
wondering if there is some other process that needs to run to inform 
cyrus the sieve script has been updated and to reload?

Regards
Sunny
