# eco-scid2pgnparser.sh - prepare a better (?) eco file for pgn-extract.

# Usage: eco-scid2pgnparser.sh from.pgn to.pgn
|
|
#
|
|
# Convert scid eco file (converted with scid's eco2pgn.py) to a file suitable for
|
|
# pgn-extract by removing the [Result] lines and replacing [Variation] with
|
|
# [Opening].
|
|
# By default, scid ECO codes are kept (they contain additional letters, such as
|
|
# A00a), the "-e" option will remove these additional letters.
