Autograph reads files in FC2 format, provided they describe
a single automaton and satisfy some correctness requirements
(see <Windows>:<check Drawing Coherency>).. 

The structure is loaded as "unexplored", so that only the initial
state appears in the popped-up window. Successive states can be 
unfolded by the user. The <Placing>:<Explore> mode is automatically
selected when loading.

Applying the <Files>:<Load Fc2> button will pop a dialog window. Just
click with the mouse cursor in the edition area, then type the file
name without its .fc2 extension. The DEL keyboard key will erase any
string in this area being selected by the window-manager drag.

WARNING: Autograph does not produce correct Fc2 format files for
automata yet (well, almost).
