# > Document lines:
# Document : Title : Issue-Month-Year : Reference reference reference
#
# Note that the first number in the date-looking-thing is not the day,
# but the issue!
#
# > Addendum lines:
# DocumentNumberE : Issue Month Year
# > (Yes, that's an E following the document number.  It stands for
#   "Extra".)
#
# > Abbreviation lines:
# A : Short : Long Form Of The Abbreviation
#
# Spaces around colons are optional and will be ignored.
#
# Every document indexed has a line; only documents present have an
# issue-month-year as well.  For this reason it is convenient to first
# enter the index(es), then go through a book and enter its
# contents.  Multiple copies of a document create multiple entries,
# even if same issue.  Addenda are not listed.  (Some addenda change
# references; incorporate those changes if possible.)
#
# For "Issue Month Year" and "reference reference", the spaces can be
# any convenient character that is not any of 0123456789:"'- (I prefer
# + because it's close to the numeric pad, then search-replace to make
# them all spaces.)  Dashes in document numbers are completely
# optional.
#
# Feel free to add abbreviations as needed.  Please ensure that an
# abbreviation won't change anything unintended.  Each file has its
# own set of abbreviations, so you only have to be consistent within
# the file that you're working on.
