NAME
       schdiff - Graphical diff tool for schematics

SYNOPSIS
       schdiff infile1.sch infile2.sch

DESCRIPTION
       The schdiff program will use ImageMagick(1) 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:

       git: Use the difftool command exactly as you would use diff , but
       supply the -x schdiff option.

       mercurial: Use the schdiff command exactly as you would use diff , but
       add the following lines to your .hgrc:

                [extensions]
                hgext.extdiff =
                [extdiff]
                cmd.schdiff = schdiff

       subversion: Use the diff command like normal, but supply the --diff-cmd
       schdiff option.

EXAMPLES
       Use git to view the changes to a file between two revisions
              git difftool -x schdiff 182110f690c51eb53ea1799fd022e87322d742e3
              039e012397f2638d1577dd7c80fb862a5503dbfd cpu.sch

       Use mercurial to see all the changes since a specific revision
              hg schdiff -r 8442880f9835 cpld.sch

       Use subversion to review a specific revision
              svn diff --diff-cmd schdiff -c 49 power.sch
