# Extra flags for the vendor tool's -preflight and -stamp steps. The one there
# is: make vendor VENDORFLAGS=-allow-dirty vendors from a sibling checkout with
# uncommitted changes, such as a debug build of libsqlite3 (see doc.go), and
# records that in vendor.json. The recipe's last step then fails, as does
# TestVendorStamp, so such a tree is never committed or released.
