# NOTES ON THE UNFOLDING OF "[|]" ALTERNATIVES
# Jorge Stolfi 05 Nov 1997
#
# To simplify processing of the text, I expanded the "[|]" notation
# used in Gabriel Landini's interlinear file v1.6. Each line that
# included one or more such alternations was replaced by a pair lines,
# one using only the first choice of every alternation, the other
# using only the second choice out of every alternation.
#
# For the extra lines resulting from the unfolding of '[|]' constructs,
# I used these codes:
#
#   D: second choice from "C" lines
#   G: second choice from "F" lines
#   I: second choice from "J" lines
#   Q: second choice from "K" lines
#   M: second choice from "L" lines
#
# Unfortunately I had to remove the "!" and "%" padding characters in
# the unfolding process, since they no longer provided the proper
# alignment between the unfolded versions and un-unfolded versions.
# Fixing this problem would have required processing all versions of
# of one line at once, and effectively computing a consensus for it.
