# In addition to standard ECO definitions, scid.eco allows for extensions:
# Each basic code can have a lower case letter extension (a-z), and an extra
# level (1-4). So the order of ECO codes for A00 is:
# A00, A00a, A00a1, A00a2, A00a3, A00a4, A00b, A00b1, ..., A00z4.
#
# You can convert this file to PGN format with the "eco2pgn.py" script,
# and to EPD with the "eco2epd" (use "make eco2pgn").
