usage() {
usagestr=$(cat <<EOF
Usage: tuxera_update.sh [OPTION...]
This script only assembles the kernel headers package
(kheaders.tar.bz2) by default. Use -a to invoke Autobuild.
--output-dir OUTDIR
Specify kernel build output directory.
--no-excludes
Do not exclude *.c, *.o, *.S, arch/*/boot. Only use if the build
fails (some of the excluded files are needed). This significantly
grows the headers package size.
--user USER [--pass PASSWD] [--admin ADMIN]
If remote connectivity is needed (-a or --latest), username and
password are required. If missing, they will be read from stdin.
NOTE: Using --pass can be dangerous as local users see it in 'ps'.
The --admin option lets you log in using the password of the given
ADMIN user.
--use-cache [--cache-dir CACHEDIR] [--latest] [--max-cache-entries N]
Obtain modules from local cache if kernel dependencies are not
modified. You must provide --output-dir to
use the cache. Modules are relinked on cache hit, ensure the
toolchain is in PATH. If -a is specified, Autobuild is invoked
on a cache miss, and the cache is updated. Otherwise, kernel headers
assembly is performed for later, manual build.
You can specify a different cache directory with --cache-dir. The
default directory is \$PWD/.tuxera_update_cache
The --latest option will ensure that the release found in cache is
the latest version available on Autobuild servers. This needs remote
connectivity. If a new version is found and -a is specified,
Autobuild is invoked and the cache is updated.
The optional --max-cache-entries can be used to limit the maximum
cache size to N recently used entries. The default is 10.
-a [--target TARGET] [OPTIONS]
Start Autobuild against TARGET. If target was not specified, uses
the default target. Use '--target list' to show available targets.
The following extra options are supported:
--use-package PACKAGE
Autobuild starts with fresh .tar.bz2 assembly by default, but
you can use this option to start Autobuild by uploading a pre-built
.tar.bz2 file PACKAGE.
--ignore-cert
If up/download fails due to certificate issues, this option can
be used to disable verification.
--use-curl
--use-wget
Force the use of 'curl' or 'wget' for remote communication.
--version SOFTWARE=VERSION[,...]
Example: --version NTFS=3012.4.2,EXFAT=3012.4.9
Specify the version of software component(s) to build.
-u, --upgrade
Upgrade online to the latest script version, obtained from
$upgrade_url
-h, --help
Prints this help.
-v
Only print the version of this script and exit.
--verbose
Print more debug information.
