That's exactly what prompted me to look it up. :-)
My older program would add moves from PGN games by first
looking in the book file, then adding an entry to a temp
file if there wasn't an entry in the book file. Once
all the PGN files were processed, the temp file and the
'old' book file were merged into an updated book file.
Worked great until a lot of entries accumulated
in the temp file. It was searched sequentially,
so it didn't take long to bog things down. Ughh.. =)
Wouldn't want to go through all that again.
