13 # This script creates a tar or zip archive with a lyx file and all included
14 # files (graphics and so on). By default, the created archive is the standard
15 # type on a given platform, such that a zip archive is created on Windows and
16 # a gzip compressed tar archive on *nix. This can be controlled by command
17 # line options, however.

37 Usage: %s [-t] [-z] [-l path] [-o output_dir] file.lyx
39 -l: Path to lyx2lyx script
40 -o: Directory for output
41 -t: Create gzipped tar file
43 By default, we create file.zip on Windows and file.tar.gz on *nix,
44 with the file output to where file.lyx is, and we look for lyx2lyx
45 in the known locations, querying LyX itself if necessary.
