#
#  The General Fuseki Pattern Database, fuseki.db
#
#  Further documentation may be found in the Texinfo documentation
#
#  First there is a pattern title of the form: Pattern [string]. The
#  string is used for identifying the pattern while tuning or debugging.
#
#  Then a block of the following characters representing the pattern
#  itself.
#  
#  ?     : don't care
#  .     : empty
#  X     : your piece,
#  O     : my piece,
#  x     : your piece or empty
#  o     : my piece or empty
#  *     : my next move
#  -, |  : edge of board
#  +     : corner of board
#  !     : additional stones to be placed on the board (together with *)
#
#  If a pattern must not match at the edge of the board,
#  an extra row of ?'s in the pattern may be added. (This
#  will not add to the time taken to check the pattern.)
#
#################
#
#  After the pattern, some supplementary information in the format:
#
# :trfno, classification, [values], helper_function
#   
#  These and other aspects of the pattern database are documented
#  in the Texinfo documentation.
#
#################
#
#  Any line beginning with #, or any part of a line following
#  whitespace is a comment. 
#
#  This database has the special property that there are stones
#  temporarily added at the very corners of the board when
#  called. This allows us to use pattern matching for the first real
#  stones in an empty corner but also means that the extreme corner
#  stones must be included in all corner patterns.
#
#  There are no meaningful classifications that can be used in this
#  database. All patterns need to have a specified value, which is
#  related to the probability that the pattern will be used. Basically
#  a pattern which has a value being N higher than another pattern is
#  2^N times more probable to be chosen. Additionally there are some
#  cutoffs involved, see engine/handicap.c for details.
