# file ext_copy.py
# This file is part of LyX, the document processor.
# Licence details can be found in the file COPYING.
# author Richard Kimberly Heck, Alex Fernandez, Uwe Stöhr
# Full author contact details are available in file CREDITS
# Usage:
# ext_copy.py [-d] [-e ext1,ext2,...] [-t target_ext] from_file to_file
# This script is to be used as a "copier" script in the sense needed by
# the converter definitions. Given a from_file and to_file, it will copy
# all files in the directory in which from_file is found that have the
# extensions given in the -e argument, or all files in that directory if no
# such argument is given. So, for example, we can do:
# python ext_copy.py -e png,html,css /path/from/file.html /path/to/file.html
# and all html, png, and css files in /path/from/ will be copied to the
# (possibly new) directory /path/to/file.html.LyXconv/.
# The -t argument determines the extension added, the default being "LyXconv".
# If just . is given, no extension is added.
# If the -d option is given then the document directory /path/to/ will be used
# to copy the files no subdirectory will be created/used.
