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
