  Error Recovery
</H1>
<P>
All programs crash, and new programs (like this one) crash a lot.
<P>
Every minute or so PfaEdit looks around and sees if anything has changed
since the last time it checked. If it finds a font that has had changes,
it will save a small file in its private directory (~/.PfaEdit/autosave)
which consists of all changed characters in the changed font.
<P>
When PfaEdit starts up it checks this directory, and if it finds anything
there it attempts to apply those changes to the original font. So if PfaEdit
crashes, or if your machine crashes, the next time you start PfaEdit it will
figure out what you were doing and recover it as best it can.
<P>
When editing CID-keyed fonts there are a few potential gotchas:
<UL>
  <LI>
    PfaEdit does not keep track of gross changes (like adding or removing a sub
    font)
  <LI>
    PfaEdit does not keep track of which sub font a change occurred in, instead
    at recovery time it will look for a subfont that is contains a character
    at the CID that was changed. In almost all cases this will be right, but
    if you add characters or if you have two sub-fonts defining the same CID,
    PfaEdit may guess wrong.
</UL>
