|
# Usage:
|
|
# python docbook_copy.py lilypond_book_command in.docbook out.docbook
|
|
# This script copies the original DocBook file (directly produced by LyX) to the output DocBook file,
|
|
# potentially applying a post-processing step. For now, the only implemented post-processing step is
|
|
# LilyPond.
|
|
# lilypond_book_command is either directly the binary to call OR the equivalent Python script that is
|
|
# not directly executable.
|
|
# /!\ The original file may be modified by this script!
