# 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.
