splitting delimited strings

[Mark Harrison]

What is the best way to process a text file of delimited strings?
I've got a file where strings are quoted with at-signs, @like this at .
At-signs in the string are represented as doubled @@.

What's the most efficient way to process this?  Failing all
else I will split the string into characters and use a FSM,
but it seems that's not very pythonesqe.

(this is from a perforce journal file, btw)

Many TIA!
