       schdiff - Graphical diff tool for schematics


       schdiff infile1.sch infile2.sch


       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

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

                hgext.extdiff =
                cmd.schdiff = schdiff

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


       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
