# Commands covered:  string

# This file contains a collection of tests for one or more of the Tcl
# built-in commands.  Sourcing this file into Tcl runs the tests and
# generates output for errors.  No output means no errors were found.
#
# This differs from the original string tests in that the tests call
# things in procs, which uses the compiled string code instead of
# the runtime parse string code.  The tests of import should match
# their equivalent number in string.test.
