.SH NAME
qdepends \- show dependency info
.SH SYNOPSIS
.B qdepends
\fI<opts> <pkgname>\fR
.SH DESCRIPTION
The qdepends applet has a couple different modes.  Normally it is geared towards
answering the queries "what does package X depend on" and "what packages depend
on X".  Both can further be classified into build, run, and post dependencies.

By default, it will tell you the build time dependencies only (DEPEND).

Currently, qdepends will only query installed packages.  There is no support for
querying packages not yet installed (the \fBequery\fR(1) tool can do that).

.SH "EXAMPLES"
For finding out what a particular package depends on for building, you could do:
.nf
	$ \fIqdepends nano\fR
	app-editors/nano-2.3.2: >=sys-libs/ncurses-5.9-r1[unicode] sys-apps/file ...
.fi
This tells us that we have \fIapp-editors/nano-2.3.2\fR installed and it depends
on ncurses (among other things).
