.SH "DESCRIPTION"
.sp
\fBport deps\fR lists all dependencies of the given port(s), i\&.e\&., the ports that need to be installed to build or use a port\&.
.sp
\fBport rdeps\fR recursively descends into the dependencies and displays a tree of dependencies for a given port\&.
.SH "OPTIONS"
.PP
\fB\-\-full\fR
.RS 4
When using
\fBrdeps\fR, display all branches of the dependency tree instead of listing each dependency only once\&.
.RE
.PP
\fB\-\-index\fR
.RS 4
Do not read Portfiles, but instead rely solely on the PortIndex information\&. Note that this option will prevent the dependencies reported from reflecting the effects of any variants specified\&.
.RE
.PP
\fB\-\-no\-build\fR
.RS 4
Exclude dependencies only required at build time, i\&.e\&., fetch, extract, and build dependencies\&.
.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\&.
.SH "DEPENDENCY RELATIONS"
.sp
Do not confuse \fIdependents\fR and \fIdependencies\fR (or, shortened, \fIdeps\fR)\&. Refer to the following example to understand the difference:
.sp
.if n \{\
.RS 4
.\}
.nf
portA \-\-> portB
.fi
.if n \{\
.RE
.\}
.sp
\fBportA\fR depends on \fBportB\fR, i\&.e\&., \fBportA\fR needs \fBportB\fR to run\&. Because of that, \fBportB\fR is a \fIdependency\fR (or \fIdep\fR) of \fBportA\fR\&. After installing \fBportA\fR, \fBportB\fR has been automatically installed\&. At this point, \fBportA\fR has become a \fIdependent\fR of \fBportB\fR\&. You can only uninstall \fBportB\fR once all of its dependents (i\&.e\&., including \fBportA\fR) have been uninstalled\&.
