There is now (see patch attached).
Allows us to specify the password on the vncpasswd command line. ie:
vncpasswd --password=MYPASSWORD ./password-file
Tested against Apple's ARD and Xvnc, works for me.
The patch is pretty ugly, done to minimize the number of line changed
rather than doing anything efficient.
What do you think?
Thanks
