where is sieve and vacation script in cyrus-imap

[JOYDEEP]

Dear list,

I hv cyrus-imapd running under suse 10.1

sieve is active here

# nmap kolkatainfoservices.in | grep 2000

                2000/tcp open  callbook

more over telnet can communicate with sieve

# linux:/home/admin # telnet kolkatainfoservices.in 2000

Trying 127.0.0.1...
Connected to kolkatainfoservices.in.
Escape character is '^]'.
"IMPLEMENTATION" "Cyrus timsieved v2.2.12"
"SASL" "LOGIN PLAIN"
"SIEVE" "fileinto reject envelope vacation imapflags notify subaddress
relational comparator-i;ascii-numeric regex"
OK

 how can I install some sieve filter and vacation notice there ?  is no
there any default scripts shipped with cyrus-imap ?

thanks
