NAME

       lepton-schdiff - Graphical diff tool for schematics

SYNOPSIS

       lepton-schdiff [-d VIEWER] infile1.sch infile2.sch

DESCRIPTION

       The  lepton-schdiff  program  will  use  ImageMagick(1) to display a graphical diff of two
       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).

       VIEWER  command,  if  specified,  will  be  used  to display the result.  By default, it's
       display program from the ImageMagick package.

       lepton-schdiff 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 lepton-
       schdiff option.

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

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

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

       Note: To make lepton-schdiff work properly, all page contents should be enclosed  in  some
       form of bounding box (e.g.  a title block), otherwise the symbols in exported images could
       have different relative positions and/or sizes, resulting in a difference  image  that  is
       rather hard to comprehend.

EXAMPLES

       Use git to view the changes to a file between two revisions
              git difftool -x lepton-schdiff 182110f 039e012 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 lepton-schdiff -c 49 power.sch
