package LastLyX;
# This package is the last step in creating a LyX file. It:
# - rejoins the lyx preamble to the rest of the file
# - adds some information (see below)
# - determines whether reLyX needs to translate any other files (e.g.,
# files included in an \include command)
# - creates a '.lyx' file
#
# reLyX may not have enough information during the previous pass. In that case,
# it puts a "marker" in the temporary file it writes, and stores the missing
# information---when it does come upon it---in a global variable.
# So during this pass, if we see any such markers, we replace them with the
# necessary information. Examples of this include:
# - header information for tables
# - name of the bibliography style file to use
