# Test that relative symlinks work by recreating the bug in b/259191764
# In some cases, developers prefer to move their checkouts. This causes
# issues in that symlinked files (namely, the bazel wrapper script)
# cannot be found. As such, we implemented relative symlinks so that a
# moved checkout doesn't need a full clean before rebuilding.
# The bazel output base will still need to be removed, as Starlark
# doesn't seem to support relative symlinks yet.
