.SH NAME
\fBdtc\fP \- Device Tree Compiler
.SH SYNOPSIS
\fB/usr/bin/dtc\fP [options] <input file>
.SH DESCRIPTION
Device Tree Compiler, dtc, takes as input a device-tree in
a given format and outputs a device-tree in another format
for booting kernels on embedded systems.
Typically, the input format is "dts", a human readable source
format, and creates a "dtb", or binary format as output.
