Fc2 format :
===========

  This format is used for file exchange between verification tools, at
the level of single automata and -more generally- hierarchical finite
networks of such. Fc2 syntax is not user-friendly but allows compact
description of large objects.

  Autograph can read -plain- automata in fc2 format, through the
<File>:<Load fc2> menu button. Initial states are then displayed in
new window, and the mouse left button is put in <Placing>:<Explore>
mode (see corresponding help file).

  Autograph translates correct window contents (automataon, or nets)
into fc2 format with the <Files>:<fc2 Format> menu button (then click
desired windows).  Correctness is checked.
