.SH DESCRIPTION
This manual page describes the output format of the file created by the
.I Yagi-Uda project
.IR input
or
.IR first
programs. The file is an ASCII file, so can be edited manually
if required. It is read by
.IR yagi
or
.IR optimise.
The program
.IR optimise
also creates the same file format.
