<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The
<b>schdiff</b> program will use <b>ImageMagick(1)</b> to
display a graphical diff of two gschem schematic files.
It’s most useful when combined with a revision control
system so it can compare two revisions of the same file,
review changes, etc. However, it is limited in that it can
only compare two files at a time; it cannot diff entire
directories nor can it diff an entire revision (unless that
revision affected only one file). It can easily be
configured to work with most revision control systems. Here
are instructions for three:</p>
<p style="margin-left:11%; margin-top: 1em"><b>git:</b> Use
the <b>difftool</b> command exactly as you would use
<b>diff</b> , but supply the <b>−x schdiff</b>
option.</p>
<p style="margin-left:11%; margin-top: 1em"><b>mercurial:</b>
Use the <b>schdiff</b> command exactly as you would use
<b>diff</b> , but add the following lines to your .hgrc:</p>
<p style="margin-left:22%; margin-top: 1em">[extensions]
<br>
hgext.extdiff = <br>
[extdiff] <br>
cmd.schdiff = schdiff</p>
<p style="margin-left:11%; margin-top: 1em"><b>subversion:</b>
Use the <b>diff</b> command like normal, but supply the
<b>--diff-cmd schdiff</b> option.</p>
