+device-tree-compiler (Device Tree Compiler for Flat Device Trees)
+
+Device Tree Compiler, 'dtc', transforms a textual description of
+a device tree ('DTS') into a binary object ('DTB').  DTS is most 
+commonly used on embedded platforms.  This tool is particularly 
+useful for building a DTS-enabled 'U-Boot' binary.
+
+See http://elinux.org/Device_Tree for more information.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
