Usage: checkout.sh [options]
Checkout svn sources into /tmp/clang-build/src. Used inside a docker container.
Available options:
-h|--help show this help message
-b|--branch svn branch to checkout, i.e. 'trunk',
'branches/release_40'
(default: 'trunk')
-p|--llvm-project name of an svn project to checkout.
For clang, please use 'clang', not 'cfe'.
Project 'llvm' is always included and ignored, if
specified.
Can be specified multiple times.
