Updated the HTML command reference files to refer to magic version 8.3, since all of the title images still had 8.2, and the title text still said 7.3 or 7.4, having not been updated for a long time.

Updated all of the documentation by copying back from the website.

Also: Changed the precision of box values printed in microns from 2 to 3 digits after the decimal place, so that 5 nanometer grids do not get values clipped in the output.

<H3>Summary:</H3>
<BLOCKQUOTE>
The <B>wire</B> command allows quick generation of wires on the
layout. Some of these commands are bound to mouse button events
in the wire tool, making a convenient interface for fast wiring
where full netlist routing is not required. Due to the presence
of the wire tool, most of these commands are not typically called
from the command line. <P>
The <B>wire segment</B> command can generate non-Manhattan segments.
All other wiring commands generate only Manhattan routes. This
command places wire segments in relation to the <I>centerline</I>
coordinates specified by <I>x1 y1</I>, <I>x2 y2</I>, and so forth.
By default, wires are drawn with an endcap extension of one-half
the wire width. The <B>-noendcap</B> option causes the wire to
end at the coordinate, with no extension. The <B>wire segment</B>
command is intended to be used from Tcl scripts for automatic

layout generation. <P>
The first format for <B>wire segment</B> has coordinates specified
on the command line. For wire segments with too many points, this
command may overrun the internal limit on either number of command-line
arguments or the total number of characters in the command line. To
work around these limits, the second format of the command specifies
a filename in place of the coordinate list. The file is a simple
text file, with one line per coordinate pair. X and Y values must be
separated by whitespace. The syntax for each value is the same as for
the command; e.g., one can use integers which will be interpreted
relative to the current snap setting, or one can specify the units,
such as "100um". <P>
When generating path points from a script, the most convenient method
is to create an empty list ("{}"), then use "lappend" to add coordinates
to the list. Once the list is complete, it is necessary to use "eval"
to decompose the list.
