<h2>DESCRIPTION</h2>

<em>v.segment</em> generates segments or points from input lines and from
positions read from 'stdin'.

<P>
The format is:
<pre>
P &lt;point id&gt;   &lt;line cat&gt; &lt;offset&gt; [&lt;side offset&gt;]
L &lt;segment id&gt; &lt;line cat&gt; &lt;start offset&gt; &lt;end offset&gt; [&lt;side offset&gt;]
</pre>

A segments is only created for the first line found of the specified category.
<P>
Points are generated in the middle of the lines. Points are created on the line for given
distance from the beginning of the vector line.

<h3>EXAMPLE</h3>

The user must send to stdin something like:
<pre>
P 1 356 24.56
P 2 495 12.31
...
</pre>
(pipe into the command).
For points, to calculate the offset (half of the length) the command <em>v.to.db</em>
can be used.
