Use this script to checkout turris-build repository relative to branch on
repo.turris.cz. It not only checkouts exact commit in turris-build
repository, but it also modifies feeds.conf file so exactly same feeds are
used as they were used to build files on server.
BRANCH argument is required and is target publish branch (Do not mix this
with git branch of same name).
BOARD is optional argument used to specify different board. In default
'omnia' is used. This is available because sometimes versions for boards
are not in sync and can differ. It should be in most cases safe to use
default but if you encounter problems you can try setting appropriate
board.
Options:
-h, --help Print this help text
