- keep the case consistent between the actual name and what's referenced. e.g, if it's `foo', don't use '.Nm Foo' at the start of a sentence. - remove unnecessary `.Nm foo' after the first occurrence (except for using `.Nm ""' if there's stuff following, or for the 2nd and so on occurrences in a SYNOPSIS - use Sx, Ic, Li, Em, Sq, and Xr as appropriate

.Sh DESCRIPTION
|
|
.Nm
|
|
writes the traditional "ripple test" pattern on standard output.
|
|
In 96 lines,
|
|
this pattern will print all 96 printable
|
|
.Tn ASCII
|
|
characters
|
|
in each position.
|
|
While originally created to test printers, it is quite
|
|
useful for testing terminals,
|
|
driving terminal ports for debugging purposes,
|
|
or any other task where a quick supply of random data is needed.
|
|
.Pp
|
|
The
|
|
.Ar length
|
|
argument specifies the output line length if the default
|
|
length of 79 is inappropriate.
|
|
.Pp
|
|
The
|
|
.Ar count
|
|
argument specifies the number of output lines to be generated if
|
|
the default count of 200 is inappropriate.
|
|
Note that if
|
|
.Ar count
|
|
is to be specified,
|
|
.Ar length
|
|
must be also be specified.
