# creates a working submodule based checkout using using bundles
function usage {
cat << EOF
Usage:
$0 -h|--help|-?
$0 [-d downloaddir] [-t targetdir] [SUBMODULES]
$0 -a [-d downloaddir] [-t targetdir] SUBMODULES
-h,--help,-? show this help
-d <path> download directory, defaults to working directory
(»$download_dir«) - tries to use existing bundle files
in this directory before downloading them
(directory must exist)
-t <path> target directory, defaults to »$target_dir« (directory must
not yet exist unless used with -a, then an existing directory
must be specified)
-a add submodules to an existing checkout without
submodules (be careful with that one)
SUBMODULES the submodules to include.
none only download the core repository (default)
all include dictionaries, helpcontent2 and translations
h[elpcontent2] helpcontent2 (can be combined)
d[ictionaries] dictionaries (can be combined)
t[ranslations] translations (can be combined)
As relative paths are used when using this script, the resulting directory can be
moved around at will without breaking git's references.
Examples:
»$0 h d«
Setup the repository in »$target_dir« with the helpcontent2 and dictionaries
submodules, downloads go to the current working directory
»$0 -d /path/to/directory all«
Setup the repository in »$target_dir« with all submodules (dictionaries,
helpcontent2, translations), downloads are looked for/stored in
/path/to/directory
»$0 -t /desired/path«
Setup the repository in »/desired/path« with no submodules.
»$0 -a -t /existing/checkout translations«
Add the translations submodule to the existing git checkout in /existing/checkout
Only use this one if you didn't initialize the specified submodules with git already.
