+This is the CVSup Mirror Kit, an easy way to set up a FreeBSD mirror
+site.  When you type "make", it asks you a few questions about
+which files you want to mirror, where you want to put them on your
+disks, where you want to update them from, etc.  After a "make
+install" your system will then be running as a nearly self-maintaining
+FreeBSD mirror site.  It will even update its own configuration
+files from the master site automatically.
+
+This kit is not for people who just want to keep their own files
+up to date with CVSup.  It is for people who wish to run servers
+that distribute the FreeBSD sources to others.
+
+This port requires CVSup version 14.1.1 or later.

+Now, a few questions so that I can set up your CVSup server properly.
+
+For security reasons, the CVSup server should run under its own
+unique user and group IDs.  These IDs should have no special access
+privileges.  Normally, the user "cvsup" and group "cvsup" are used,
+but you can choose other names if you wish.  At "make install"
+time, I will create the user and group, if they don't already exist.
+
+For security reasons, you must use unique user and group IDs for
+this.  Do NOT use "nobody", "nonroot", or "nogroup".
+
+EOF
+
+user=$(ask "Unique unprivileged user ID for running the server" cvsup)
+group=$(ask "Unique unprivileged group ID for running the server" cvsup)
+
+cat <<EOF
+
+The CVSup server does its logging via syslog.  At "make install"
+time, I will set up the logging for you, if necessary.  I will use
+the "!program" feature of syslog to keep your CVSup log messages
+separate from the messages of your other daemons.
+
+EOF
+
+while :; do
+    facility=$(ask "Syslog facility for the server log" daemon)
+    case ${facility} in
+    daemon|local[0-7]|ftp|user)	break;;
+    esac
+    echo "Please answer daemon, local0-local7, ftp, or user"
+done
+
+cat <<EOF
+
+You can control the load on your machine by limiting the number of
+clients that the CVSup server will serve at once.  CVSup won't load
+your network especially heavily, but it is more CPU and disk
+intensive than most other file server software.

+while :; do
+    maxclients=$(ask "Maximum simultaneous client connections" 8)
