# safe-zipfs.test --
#
# This file contains tests for safe Tcl that test its compatibility with the
# zipfs facilities introduced in Tcl 8.7.  Test numbering is for comparison
# with similar tests in safe.test that do not use the zipfs file system.
#
# Sourcing this file into tcl runs the tests and generates output for errors.
# No output means no errors were found.
