-# This script will merge an svn revision to a git repo using git-svn while
-# preserving the svn commit message.
-# 
-# NOTE: This script has only been tested with the per-project git repositories
-# and not with the monorepo.
-#
-# In order to use this script, you must:
-# 1) Checkout the stable branch you would like to merge the revision into.
-# 2) Correctly configure the branch as an svn-remote by adding the following to
-# your .git/config file for your git repo (replace xy with the major/minor
-# version of the release branch. e.g. release_50 or release_60):
-#
-#[svn-remote "release_xy"]
-#url = https://llvm.org/svn/llvm-project/llvm/branches/release_xy
-#fetch = :refs/remotes/origin/release_xy
-#
-# Once the script completes successfully, you can push your changes with
-# git-svn dcommit
