+.SH "NAME"
+port-selfupdate \- Upgrade MacPorts itself and update the port definition files\&.
+.SH "SYNOPSIS"
+.sp
+.nf
+\fBport\fR [\fB\-qvdf\fR] \fBselfupdate\fR [\-\-nosync]
+.fi
+.SH "DESCRIPTION"
+.sp
+\fBport selfupdate\fR checks for new releases of MacPorts and upgrades it when necessary\&. \fBselfupdate\fR also updates the local port definitions (the so\-called ports tree) to the latest state so you have the latest versions of ports available\&. This part of the operation corresponds to \fBport-sync\fR(1)\&.
+.sp
+You should regularly run \fBselfupdate\fR to update your local port definitions\&. Running \fBselfupdate\fR is required to get updated software with bug fixes and new features\&.
+.SH "OPTIONS"
+.PP
+\-\-nosync
+.RS 4
+Only check for updates \- and install if available \- for MacPorts itself\&. Do not update the ports tree\&.
+.RE
+.SH "GLOBAL OPTIONS"
+.sp
+Please see the section \fBGLOBAL OPTIONS\fR in the \fBport\fR(1) man page for a description of global port options\&.
+.PP
+\-q
+.RS 4
+Supress status output, be as silent as possible\&.
+.RE
+.PP
+\-f
+.RS 4
+Do not check whether the downloaded MacPorts version is newer than the currently installed one, but always rebuild and reinstall MacPorts\&.
+
+You can use this to downgrade from a beta or development version to the latest release\&. Note that there is no guarantee that there have not been made incompatible and irreversible changes to MacPorts\*(Aq internal data structures, making a downgrade impossible\&.
+.RE
+.SH "EXAMPLES"
+.sp
+When no new versions are available, \fBselfupdate\fR looks like this:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+$ sudo port selfupdate
+\-\-\-> Updating MacPorts base sources using rsync
+MacPorts base version 2\&.3\&.99 installed,
+MacPorts base version 2\&.3\&.99 downloaded\&.
+\-\-\-> Updating the ports tree
+\-\-\-> MacPorts base is already the latest version
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+If \fBselfupdate\fR detects that a newer version of MacPorts is available, it attempts to update your copy to this version\&. In that case, the output will be different:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+$ sudo port selfupdate
+\-\-\-> Updating MacPorts base sources using rsync
+MacPorts base version 2\&.3\&.0 installed,
+MacPorts base version 2\&.3\&.99 downloaded\&.
+\-\-\-> Updating the ports tree
+\-\-\-> MacPorts base is outdated, installing new version 2\&.3\&.99
+Installing new MacPorts release in /opt/local as root:admin; permissions 755
+.fi
+.if n \{\
+.RE
+.\}
+.SH "TROUBLESHOOTING"
+.sp
+If \fBselfupdate\fR fails, it usually does so in one of two places: The network connection, or the installation of the update\&.
+.PP
+Network Problems
+.RS 4
+MacPorts uses the
+\fIrsync\fR
+protocol to update its sources to the latest version\&. This will fail if you are on a network that blocks TCP connections to the rsync port 873\&. Talk to your network administrators and ask them to allow connections to port 873 if this happens to you\&. Alternatively, you can just download a new installer \&.pkg from macports\&.org and run that to upgrade your installation\&.
+.sp
+Network connection problems might also affect you if you are in a country with US export restrictions\&. We suggest using one of our other
+\m[blue]\fBmirrors\fR\m[]\&\s-2\u[1]\d\s+2
+outside of the US in these cases\&.
+.RE
+.PP
+Compilation Problems
+.RS 4
+When a problem occurs while building and installing the new MacPorts version, you will see the message
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+Error installing new MacPorts base: command execution failed
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+To find out what went wrong, re\-run
+\fBselfupdate\fR
+with the
+\fB\-d\fR
+flag\&. This will allow you to see all output generated by the build system\&. Look for the first occurance of \(lqerror\(rq\&. If you cannot figure out what\(cqs wrong on your own, feel free to ask on
+\m[blue]\fBthe macports\-users mailing list\fR\m[]\&\s-2\u[2]\d\s+2
+and attach the output generated by
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+$ sudo port \-d selfupdate
