Usage: $(basename $0) -d|--download <path> [-t|--target <path>] [-l|--libreelec <path>]
[-m|--mirror] [-s|--source] [-a|-all] [-p|--package <package_name> [-r|--revision <revision>]]
[--git] [-n|--notnewer] [--check-main | --check-addons] [--check-ver | --check-rev]

[--path-filter path] [--verify-checksum] [-v|--verbose] [-h|--help]
Options:
-d, --download: Directory path into which new package files will be downloaded - default is $HOME/download[1]
-t, --target: Directory path for existing packages that are to be refreshed, default is $HOME/sources[2]
-l, --libreelec: LibreELEC.tv repo, default is ${HOME}/LibreELEC.tv
-m, --mirror: Target is mirror not source - mirror uses a hierarchical per-package folder structure
-s, --source: Target is source not mirror - source uses a flattened file structure. Default is mirror
-a, --all: Ignore download failures, continue processing all packages
-p, --package: Package to process, otherwise process all packages
-r, --revision: Version to use in place of PKG_VERSION, only applicable in conjunction with -p
--git: Clone (if not available) or pull the LibreELEC.tv repository
-n, --notnewer: Don't check for newer packages ('X.Y.Z+1' 'X.Y+1.0' 'X+1.0.0')
--check-main: Check newer for main packages, ignore add-on packages
--check-addons: Check newer for add-on packages, ignore main packages
--check-ver: Check newer for version-based packages, ignore rev-based/github packages
--check-rev: Check newer for rev-based/github packages, ignore version-based packages
--no-progress: Do not show progress indicator
-T, --threads: Number of download worker threads, default is 16
-U, --gituser: Git username (or source from ~/.git.conf) - avoids API limits
-P, --gitpass: Git password (or source from ~/.git.conf) - avoids API limits
--dry-run: Don't actually download anything (will still git clone/pull if configured)
--path-filter Restrict workload to specified path, eg. packages/x11 (recursive)
--verify-checksum: If checksum on mirror is no longer valid, attempt re-download of package from source
-v, --verbose: Output more verbose sync information. Repeat for more detail
-h, --help: This message
Note#1. The download directory will have the LibreELEC version appended (eg. /devel) unless it is a mirror, in which case "/mirror" will be appended.
Note#2. The target directory will have the LibreELEC version appended (eg. /devel) unless it is a mirror, in which case "/mirror" will be appended.
