Watson's strategic chess pgn file I am looking for the PGN file corresponding to Watson's strategic chess opening repertoire for white; is it available? If the PGN is not available, I would be interested to know what other opening books have a PGN companion available. 

as a side note I've though about writing a python script to read in chess books as PDF and extracting the variations as PGN. Has anyone done this yet?
Given that PGN files are just plain text, then you can create your own.

From wikipedia you need 7 tags:


  PGN data for archival storage is required to provide seven bracketed fields, referred to as "tags"...:
  
  
  Event
  Site
  Date: the starting date of the game, in YYYY.MM.DD form. ?? is used for unknown values
  Round
  White: the player of the white pieces, in Lastname, Firstname format.
  Black: the player of the black pieces, same format as White.
  Result: the result of the game. This can only have four possible values: 1-0 (White won), 0-1 (Black won), 1/2-1/2 (Draw), or * (other, e.g., the game is ongoing).
  


An example might be:

[Event "QGA: Main line with 7.Bd3"] 
[Site "?"] 
[Date "????.??.??"] 
[Round "?"] 
[White "Me"] 
[Black "The other guy"] 
[Result "*"]
