I have a program that does the following.

You use an editor to create a pgn file "list" with an opening line.

Then you type in a command

	parse a|b|c|d|e numPlys

a|b|c|d|e is the eco book you want to search.  (the program expects
you to have the gzipped databases.  a.pgn.gz b.pgn.gz c.pgn.gz etc.

numPlys is the depth of the tree you want to examine after the
opening lines in "list"

The program uses zcat and a program I wrote to read the book. It
finds all of the games that transpose
into the position at the end of the "list" sequence.  It then collects
all of the games that were played from that position into a seperate
pgn file called "out.pgn".  It writes a file "out.line"
that shows all of the sequences of length numPlys that were found in
these games.  For each sequence it gives the count of white wins,
black wins, and draws.  Also for each sequence it lists the game 
numbers of each of the white wins/black wins/draws.  The user can
then open "out.pgn" with xboard, and select any of the game numbers
that are listed in "out.line".  Thus out.line is a slightly 
intellegent index into "out.pgn" that is categorized by sequence 
and result.

Would this be of interest?
