+#   Cherry-picks a list of commits, amends each with the original commit hash for tracking,
+#   and generates a summary from the short github commit messages with links to each commit.
+#
+# Usage:
+#   ./minor-release.sh <commit1> <commit2> ...
+#
+# Example:
+#   ./minor-release.sh abc1234 def5678
+
+set -e

+# Check if at least two arguments are provided (repo and at least one commit)
