Internal format :
=================

  Autograph uses an internal format for saving and restoring drawings
including graphical attributes and possibly incoherent (as nets).

  Files are loaded with the <Files>:<Load atg> menu command, and saved
with <Files>:<atg Format> or <Files>:<atg Format as> (then click on
each window to be saved).

  Filenames are suffixed by ".atg".


Old ".sa" file format :
-----------------------

  The sa2atg Unix command (included in the atg distribution)
translates the older ".sa" syntax to actual ".atg" syntax.
