+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.
