 .SH COMMANDS
 .TP
-\fB::tcltest::test\fP \fIname desc ?constraints? script expectedAnswer\fR 
-The \fB::tcltest::test\fR command runs\fIscript\fR and compares 
-its result to \fIexpectedAnswer\fR. It prints an error message if the two do
-not match.  If \fB::tcltest::verbose\fR contains "p" or "s", it also prints
-out a message if the test passed or was skipped.  The test will be
-skipped if it doesn't match the \fB::tcltest::match\fR variable, if it
-matches an element in \fB::tcltest::skip\fR, or if one of the elements
-of \fIconstraint\fR turns out not to be true.  The 
-\fB::tcltest::test\fR command has no defined return values.  See the
-\fI"Writing a new test"\fR section for more details on this command.

+\fBtcltest::test\fP \fIname desc ?option value? ?option value? ...\fR
+.TP
+\fBtcltest::test\fP \fIname desc {?option value? ?option value? ...}\fR
+The \fBtcltest::test\fR command runs the value supplied for attribute
+\fIscript\fR and compares its result to possible results.  
+It prints an error message if actual results and expected results do
+not match.  The \fBtcltest::test\fR command returns 0 if it completes
+successfully. Any other return value indicates that an error has
+occurred in the tcltest package.  See the \fI"Tests"\fR section for
+more details on this command.   
+.TP
+\fBtcltest::cleanupTests\fP \fI?runningMultipleTests?\fR
 This command should be called at the end of a test file.  It prints
 statistics about the tests run and removes files that were created by
-\fB::tcltest::makeDirectory\fR and \fB::tcltest::makeFile\fR.  Names
+\fBtcltest::makeDirectory\fR and \fBtcltest::makeFile\fR.  Names
 of files and directories created outside of 
-\fB::tcltest::makeFile\fR and \fB::tcltest::makeDirectory\fR and
-never deleted are printed to \fB::tcltest::outputChannel\fR.  This command
+\fBtcltest::makeFile\fR and \fBtcltest::makeDirectory\fR and
+never deleted are printed to \fBtcltest::outputChannel\fR.  This command
 also restores the original shell environment, as described by the ::env
-array. \fIcalledFromAll\fR should be specified when
-\fB::tcltest::cleanupTests\fR is called from an "all.tcl" file.  Tcl files
-files are generally used to run multiple tests.  For more details on how to
-run multiple tests, please see the section \fI"Running test files"\fR.
-This proc has no defined return value.
-.TP
-\fB::tcltest::getMatchingTestFiles\fP
-This command is used when you want to run multiple test files.  It returns
-the list of tests that should be sourced in an 'all.tcl' file.  See the
-section \fI"Running test files"\fR for more information.
-.TP
-\fB::tcltest::loadTestedCommands\fP
+array. \fIcalledFromAll\fR should be specified if
+\fBtcltest::cleanupTests\fR is called explicitly from an "all.tcl"
+file.  Tcl files files are generally used to run multiple tests.  For
+more details on how to run multiple tests, please see the section
+\fI"Running test files"\fR.  This proc has no defined return value.
+.TP
+\fBtcltest::runAllTests\fP
+This command should be used in your 'all.tcl' file.  It is used to
+loop over test files and directories, determining which test files to
+run and then running them.  Note that this test calls
+tcltest::cleanupTests; if using this proc in your 'all.tcl' file, you
+should not call tcltest::cleanupTests explicitly in that file. See the
+sample 'all.tcl' file in the \fI"Examples"\fR section.
+.TP
+\fBtcltest::interpreter\fR \fI?executableName?\fR
+Sets or returns the name of the executable used to invoke the test

+.TP
+\fBtcltest::singleProcess\fR \fI?boolean?\fR
+Sets or returns a boolean indicating whether test files should be sourced
+into the current interpreter by runAllTests or run in their own
+processes. If \fIboolean\fR is true (1), tests are sourced into the
+current interpreter.  If \fIboolean\fR is false (0), tests are run in
+the interpreter specified in tcltest::interpreter.  The default value
+for tcltest::singleProcess is false.
+.TP
+\fBtcltest::debug\fR \fI?level?\fR
+Sets or returns the current debug level. The debug level determines
+how much tcltest package debugging information is printed to stdout.
+The default debug level is 0. Levels are defined as:
+.RS

+specified by -skip or tcltest::skip (userSpecifiedSkip).  
+.IP 2
+Display the flag array parsed by the command line processor, the
+contents of the ::env array, and all user-defined variables that exist
+in the current namespace as they are used.
+.IP 3
+Display information regarding what individual procs in the test
+harness are doing.
+.RE
+.TP
+\fBtcltest::verbose\fR \fI?levelList?\fR

+does not match its expected return code
+.RE
+.TP
+\fBtcltest::preserveCore\fR \fI?level?\fR
+Sets or returns the current core preservation level.  This level
+determines how stringent checks for core files are.  The default core
+preservation level is 0.  Levels are defined as:
+.RS
+.IP 0
+No checking - do not check for core files at the end of each test
+command, but do check for them whenever tcltest::cleanupTests is
+called from tcltest::runAllTests. 
+.IP 1
+Check for core files at the end of each test command and whenever
+tcltest::cleanupTests is called from tcltest::runAllTests.
+.IP 2
+Check for core files at the end of all test commands and whenever
+tcltest::cleanupTests is called from all.tcl.  Save any core files
+produced in tcltest::temporaryDirectory.

+.TP
+\fBtcltest::limitConstraints \fI?constraintList?\fR
+Sets or returns a boolean indicating whether testing is being limited
+to constraints listed in \fIconstraintList\fR.
+If limitConstraints is not false, only those tests with constraints matching
+values in \fIconstraintList\fR will be run.  
+.TP
+\fBtcltest::workingDirectory\fR \fI?directoryName?\fR
+Sets or returns the directory in which the test suite is being run.
+The default value for workingDirectory is the directory in which the
+test suite was launched.
+.TP
+\fBtcltest::temporaryDirectory\fR \fI?directoryName?\fR

+\fBtcltest::testsDirectory\fR \fI?directoryName?\fR
+Sets or returns the directory where the tests reside.  This defaults
+to the directory returned by \fItcltest::workingDirectory\fR
+if the script cannot determine where the \fItests\fR directory is
+located. This variable should be explicitly set if tests are being run
+from an all.tcl file. 
+.TP
+\fBtcltest::match\fR \fI?globPatternList?\fR
+Sets or returns the glob pattern list that determines which tests
+should be run.  Only tests which match one of the glob patterns in
+\fIglobPatternList\fR are run by the test harness.  The default value
+for \fIglobPatternList\fR is '*'.
+.TP
+\fBtcltest::matchFiles\fR \fI?globPatternList?\fR
+Sets or returns the glob pattern list that determines which test files

 The \fBtest\fR procedure runs a test script and prints an error
 message if the script's result does not match the expected result.
-The following is the spec for the \fBtest\fR command:
+Two syntaxes are provided for specifying the attributes of the tests.
+The first uses a separate argument for each of the attributes and
+values.  The second form places all of the attributes and values
+together into a single argument; the argument must have proper list
+structure, with teh elements of the list being the attributes and
+values.  The second form makes it easy to construct multi-line
+scripts, since the braces around the whole list make it unnecessary to
+include a backslash at the end of each line.  In the second form, no
+command or variable substitutions are performed on the attribute
+names.  This makes the behavior of the second form different from the
+first form in some cases.

+.SH "KNOWN ISSUES"
+There are two known issues related to nested test commands.  
+The first issue relates to the stack level in which test scripts are
+executed.  Tests nested within other tests may be executed at the same
+stack level as the outermost test.  For example, in the following test
+code: 
+.DS
+test level-1.1 {level 1} {
+    -body {
+        test level-2.1 {level 2} {
+        }
+    }
+}
+.DE
+any script executed in level-2.1 may be executed at the same stack
+level as the script defined for level-1.1.  
+.PP
+In addition, while two
+test commands have been run, results will only be reported for tests
+at the same level as test level-1.1.  However, test results for all
+tests run prior to level-1.1 will be available when test level-2.1
+runs.  What this means is that if you try to access the test results
+for test level-2.1, it will may say that 'm' tests have run, 'n' tests
+have been skipped, 'o' tests have passed and 'p' tests have failed,
+where 'm', 'n', 'o', and 'p' refer to tests that were run at the same
+test level as test level-1.1. 
+.PP
+Implementation of output and error comparison in the test command
+depends on usage of puts in your application code.  Output is
+intercepted by redefining the puts command while the defined test
+script is being run.  Errors thrown by C procedures or printed
+directly from C applications will not be caught by the test command.
+Therefore, usage of expect_out and expect_err in the test command is
+useful only for pure Tcl applications that use the puts command for
+output.

-.SH DESCRIPTION
-.PP
-The \fBtcltest\fR package provides the user with utility tools for
-writing and running tests in the Tcl test suite.  It can also be used
-to create a customized test harness for an extension. 
-.PP
-The Tcl test suite consists of multiple .test files, each of which
-contains multiple test cases.  Each test case consists of a call to
-the test command, which specifies the name of  test, a short
-description, any constraints that apply to the test case, the script
-to be run, and expected results.  See the \fI"Tests"\fR section for more
-details. 
-.PP
-It is also possible to add to this test harness to create your own
-customized test harness implementation.  For more defails, see the
-section \fI"How to Customize the Test Harness"\fR.
-.SH COMMANDS
-.TP
-\fBtcltest::test\fP \fIname desc ?option value? ?option value? ...\fR
-.TP
-\fBtcltest::test\fP \fIname desc {?option value? ?option value? ...}\fR
-The \fBtcltest::test\fR command runs the value supplied for attribute
-\fIscript\fR and compares its result to possible results.  
-It prints an error message if actual results and expected results do
-not match.  The \fBtcltest::test\fR command returns 0 if it completes
-successfully. Any other return value indicates that an error has
-occurred in the tcltest package.  See the \fI"Tests"\fR section for
-more details on this command.   
-.TP
-\fBtcltest::cleanupTests\fP \fI?runningMultipleTests?\fR
-This command should be called at the end of a test file.  It prints
-statistics about the tests run and removes files that were created by
-\fBtcltest::makeDirectory\fR and \fBtcltest::makeFile\fR.  Names
-of files and directories created outside of 
-\fBtcltest::makeFile\fR and \fBtcltest::makeDirectory\fR and
-never deleted are printed to \fBtcltest::outputChannel\fR.  This command
-also restores the original shell environment, as described by the ::env
-array. \fIcalledFromAll\fR should be specified if
-\fBtcltest::cleanupTests\fR is called explicitly from an "all.tcl"
-file.  Tcl files files are generally used to run multiple tests.  For
-more details on how to run multiple tests, please see the section
-\fI"Running test files"\fR.  This proc has no defined return value.
-.TP
-\fBtcltest::runAllTests\fP
-This command should be used in your 'all.tcl' file.  It is used to
-loop over test files and directories, determining which test files to
-run and then running them.  Note that this test calls
-tcltest::cleanupTests; if using this proc in your 'all.tcl' file, you
-should not call tcltest::cleanupTests explicitly in that file. See the
-sample 'all.tcl' file in the \fI"Examples"\fR section.
-.TP
-\fBtcltest::interpreter\fR \fI?executableName?\fR
-Sets or returns the name of the executable used to invoke the test
-suite. This is the interpreter used in runAllTests to run test files
-if singleProcess is set to false.  The default value for interpreter
-is the name of the interpreter in which the tests were started.  
-.TP
-\fBtcltest::singleProcess\fR \fI?boolean?\fR
-Sets or returns a boolean indicating whether test files should be sourced
-into the current interpreter by runAllTests or run in their own
-processes. If \fIboolean\fR is true (1), tests are sourced into the
-current interpreter.  If \fIboolean\fR is false (0), tests are run in
-the interpreter specified in tcltest::interpreter.  The default value
-for tcltest::singleProcess is false.
-.TP
-\fBtcltest::debug\fR \fI?level?\fR
-Sets or returns the current debug level. The debug level determines
-how much tcltest package debugging information is printed to stdout.
-The default debug level is 0. Levels are defined as:
-.RS
-.IP 0
-Do not display any debug information.
-.IP 1
-Display information regarding whether a test is skipped because it
-doesn't match any of the tests that were specified using -match or
-tcltest::match (userSpecifiedNonMatch) or matches any of the tests
-specified by -skip or tcltest::skip (userSpecifiedSkip).  
-.IP 2
-Display the flag array parsed by the command line processor, the
-contents of the ::env array, and all user-defined variables that exist
-in the current namespace as they are used.
-.IP 3
-Display information regarding what individual procs in the test
-harness are doing.
-.RE
-.TP
-\fBtcltest::verbose\fR \fI?levelList?\fR
-Sets or returns the current verbosity level.  The default verbosity
-level is "body".   See the "Test output" section for a more detailed
-explanation of this option. Levels are defined as:

-.IP pass
-Print output when a test passes
-.IP skip
-Print output when a test is skipped
-.IP start
-Print output whenever a test starts

-Print errorInfo and errorCode, if they exist, when a test return code
-does not match its expected return code
-.RE
-.TP
-\fBtcltest::preserveCore\fR \fI?level?\fR
-Sets or returns the current core preservation level.  This level
-determines how stringent checks for core files are.  The default core
-preservation level is 0.  Levels are defined as:
-.RS
-.IP 0
-No checking - do not check for core files at the end of each test
-command, but do check for them whenever tcltest::cleanupTests is
-called from tcltest::runAllTests. 
-.IP 1
-Check for core files at the end of each test command and whenever
-tcltest::cleanupTests is called from tcltest::runAllTests.

-.TP
-\fBtcltest::testsDirectory\fR \fI?directoryName?\fR
-Sets or returns the directory where the tests reside.  This defaults
-to the directory returned by \fItcltest::workingDirectory\fR
-if the script cannot determine where the \fItests\fR directory is
-located. This variable should be explicitly set if tests are being run
-from an all.tcl file. 
-.TP
-\fBtcltest::match\fR \fI?globPatternList?\fR
-Sets or returns the glob pattern list that determines which tests
-should be run.  Only tests which match one of the glob patterns in
-\fIglobPatternList\fR are run by the test harness.  The default value
-for \fIglobPatternList\fR is '*'.
-.TP
-\fBtcltest::matchFiles\fR \fI?globPatternList?\fR
-Sets or returns the glob pattern list that determines which test files
-should be run.  Only test files which match one of the glob patterns in
-\fIglobPatternList\fR are run by the test harness.  The default value
-for \fIglobPatternList\fR is '*.test'.
-.TP
-\fBtcltest::matchDirectories\fR \fI?globPatternList?\fR
-Sets or returns the glob pattern list that determines which test
-subdirectories of the current test directory should be run.  Only test
-subdirectories which match one of the glob patterns in 
-\fIglobPatternList\fR are run by the test harness.  The default value
-for \fIglobPatternList\fR is '*'.
-.TP
-\fBtcltest::skip\fR \fI?globPatternList?\fR
-Sets or returns the glob pattern list that determines which tests (of
-those matched by tcltest::match) should be skipped.  The default value
-for \fIglobPatternList\fR is {}.
-.TP
-\fBtcltest::skipFiles\fR \fI?globPatternList?\fR

-default value for \fIglobPatternList\fR is {}.
-.TP
-\fBtcltest::skipDirectories\fR \fI?globPatternList?\fR
-Sets or returns the glob pattern list that determines which test
-subdirectories (of those matched by tcltest::matchDirectories) should
-be skipped.  The default value for \fIglobPatternList\fR is {}.
-.TP
-\fBtcltest::loadTestedCommands\fP
-This command uses the script specified via the \fI-load\fR or
-\fI-loadfile\fR options or the tcltest::loadScript or
-tcltest::loadFile procs to load the commands checked by the test suite.
-It is allowed to be empty, as the tested commands could have been
-compiled into the interpreter running the test suite.
-.TP
-\fBtcltest::loadScript\fR \fI?script?\fR
-Sets or returns the script executed by \fBloadTestedCommands\fR.   
-.TP
-\fBtcltest::loadFile\fR \fI?filename?\fR
-Sets ore returns the file name associated with the script executed
-\fBloadTestedCommands\fR.  If setting \fIfilename\fR, this proc will

-.TP
-\fBtcltest::outputChannel\fR \fI?channelID?\fR
-Sets or returns the output file ID.  This defaults to stdout.
-Any test that prints test related output should send
-that output to \fItcltest::outputChannel\fR rather than letting
-that output default to stdout.

-.TP
-\fBtcltest::viewFile\fP \fIfile ?directory?\fR
-Returns the contents of \fIfile\fR.  This file name
-should be relative to \fIdirectory\fR.   If left unspecified,
-\fIdirectory\fR defaults to tcltest::temporaryDirectory.
-.TP
-\fBtcltest::normalizeMsg\fP \fImsg\fR
-Remove extra newlines from \fImsg\fR.
-.TP
-\fBtcltest::normalizePath\fP \fIpathVar\fR
-Resolves symlinks in a path, thus creating a path without internal
-redirection.  It is assumed that \fIpathVar\fR is absolute.
-\fIpathVar\fR is modified in place.
-.TP
-\fBtcltest::bytestring\fP \fIstring\fR
-Construct a string that consists of the requested sequence of bytes,
-as opposed to a string of properly formed UTF-8 characters using the
-value supplied in \fIstring\fR.  This allows the tester to create
-denormalized or improperly formed strings to pass to C procedures that
-are supposed to accept strings with embedded NULL types and confirm
-that a string result has a certain pattern of bytes.
-.TP
-\fBtcltest::saveState\fP
-Save procedure and global variable names.
-A test file might contain calls to \fBtcltest::saveState\fR and
-\fB::tcltest:restoreState\fR if it creates or deletes global variables
-or procs. 
-.TP
-\fBtcltest::restoreState\fP
-Restore procedure and global variable names.
-A test file might contain calls to \fBtcltest::saveState\fR and
-\fB::tcltest:restoreState\fR if it creates or deletes global variables
-or procs. 
-.TP
-\fBtcltest::threadReap\fP
-\fBtcltest::threadReap\fR only works if \fItestthread\fR is
-defined, generally by compiling tcltest.  If \fItestthread\fR is
-defined, \fBtcltest::threadReap\fR kills all threads except for the
-main thread.  It gets the ID of the main thread by calling
-\fItestthread names\fR during initialization.  This value is stored in
-\fItcltest::mainThread\fR. \fBtcltest::threadReap\fR returns the
-number of existing threads at completion.
-.TP
-\fBtcltest::mainThread\fR
-Sets or returns the main thread ID.  This defaults to 1.  This is the
-only thread that is not killed by tcltest::threadReap and is set
-according to the return value of \fItestthread names\fR at
-initialization. 
-.SH TESTS
-The \fBtest\fR procedure runs a test script and prints an error
-message if the script's result does not match the expected result.
-Two syntaxes are provided for specifying the attributes of the tests.
-The first uses a separate argument for each of the attributes and
-values.  The second form places all of the attributes and values
-together into a single argument; the argument must have proper list
-structure, with teh elements of the list being the attributes and
-values.  The second form makes it easy to construct multi-line
-scripts, since the braces around the whole list make it unnecessary to
-include a backslash at the end of each line.  In the second form, no
-command or variable substitutions are performed on the attribute
-names.  This makes the behavior of the second form different from the
-first form in some cases.
-.PP
-The first form for the \fBtest\fR command:
-.DS
-test \fIname\fR \fIdescription\fR 
-    ?-constraints \fIkeywordList|expression\fR
-    ?-setup \fIsetupScript\fR?
-    ?-body \fItestScript\fR?
-    ?-cleanup \fIcleanupScript\fR?
-    ?-result \fIexpectedAnswer\fR?
-    ?-output \fIexpectedOutput\fR? 
-    ?-errorOutput \fIexpectedError\fR? 
-    ?-returnCodes \fIcodeList\fR?
-    ?-match \fIexact|glob|regexp\fR?
-.DE
-.PP
-The second form for the \fBtest\fR command:
-.DS
-test \fIname\fR \fIdescription\fR {
-    ?-constraints \fIkeywordList|expression\fR
-    ?-setup \fIsetupScript\fR?

-    ?-output\fIexpectedOutput\fR? 
-    ?-errorOutput \fIexpectedError\fR? 
-    ?-returnCodes \fIcodeList\fR?
-    ?-match \fIexact|glob|regexp?
-}
-.DE
-The \fIname\fR argument should follow the pattern:
-.DS
-<target>-<majorNum>.<minorNum>
-.DE
-For white-box (regression) tests, the target should be the name of the
-C function or Tcl procedure being tested.  For black-box tests, the
-target should be the name of the feature being tested.  Related tests
-should share a major number.
-.PP
-The \fIdescription\fR should be a short textual description of the
-test.  It is generally used to help humans 
-understand the purpose of the test.  The name of a Tcl or C function
-being tested should be included in the description for regression
-tests.  If the test case exists to reproduce a bug, include the bug ID
-in the description. 
-.PP
-Valid attributes and associated values are:
-.TP
-\fB-constraints \fIkeywordList|expression\fR\fP
-The optional \fIconstraints\fR attribute can be list of one or more
-keywords or an expression.  If the \fIconstraints\fR value consists of
-keywords, each of these keywords being the name of a constraint
-defined by a call to \fItcltest::testConstraint\fR.  If any of these
-elements is false or does 
-not exist, the test is skipped.  If the \fIconstraints\fR argument
-consists of an expression, that expression is evaluated. If the
-expression evaluates to true, then the test is run.  Appropriate
-constraints should be added to any tests that should
-not always be run.  See the "Test Constraints" section for a list of built-in 
-constraints and information on how to add your own constraints.
-.TP
-\fB-setup \fIscript\fR\fP
-The optional \fIsetup\fR attribute indicates a script that will be run
-before the script indicated by the \fIscript\fR attribute.  If setup
-fails, the test will fail.
-.TP
-\fB-body \fIscript\fR\fP
-The \fIbody\fR attribute indicates the script to run to carry out the 
-test.  It must return a result that can be checked for correctness.
-If left unspecified, the script value will be {}.
-.TP
-\fB-cleanup \fIscript\fR\fP
-The optional \fIcleanup\fR attribute indicates a script that will be
-run after the script indicated by the \fIscript\fR attribute.  If
-cleanup fails, the test will fail.  
-.TP
-\fB-match \fIregexp|glob|exact\fP
-The \fImatch\fR attribute determines how expected answers supplied in
-\fIresult\fR, \fIoutput\fR, and \fRerrorOutput\fR are compared.  Valid
-options for the value supplied are "regexp", "glob", and
-"exact". If \fImatch\fR is not specified, the comparisons will be
-done in "exact" mode by default.
-.TP
-\fB-result \fIexpectedValue\fR\fP
-The \fIresult\fR attribute supplies the comparison value with which
-the return value from script will be compared. 
-If left unspecified, the default
-\fIexpectedValue\fR will be the empty list.
-.TP
-\fB-output \fIexpectedValue\fR\fP
-The \fIoutput\fR attribute supplies the comparison value with which
-any output sent to stdout or tcltest::outputChannel during the script
-run will be compared.  Note that only output printed using
-puts is used for comparison.  If \fIoutput\fR is not specified, output
-sent to stdout and tcltest::outputChannel is not processed for comparison.
-.TP
-\fB-errorOutut \fIexpectedValue\fR\fP
-The \fIerrorOutput\fR attribute supplies the comparison value with which
-any output sent to stderr or tcltest::errorChannel during the script
-run will be compared. Note that only output printed using
-puts is used for comparison.  If \fIerrorOutut\fR is not specified, output
-sent to stderr and tcltest::errorChannel is not processed for comparison.
-.TP
-\fB-returnCodes \fIexpectedCodeList\fR\fP
-The optional \fIreturnCodes\fR attribute indicates which return codes
-from the script supplied with the \fIscript\fR attribute are correct.
-Default values for \fIexpectedCodeList\fR are 0 (normal return) and 2
-(return exception).  Symbolic values \fInormal\fR (0), \fIerror\fR
-(1), \fIreturn\fR (2), \fIbreak\fR (3), and \fIcontinue\fR (4) can be
-used in the \fIexpectedCodeList\fR list.
-.PP
-To pass, a test must successfully execute its setup, script, and
-cleanup code.  The return code of the test and its return values must
-match expected values, and if specified, output and error data from
-the test must match expected output and error values. If all of these
-conditions are not met, then the test fails.
-.SH "TEST CONSTRAINTS"
-Constraints are used to determine whether or not a test should be skipped.
-If a test is constrained by "unixOnly", then it will only be run if
-the value of the constraint is true.  Several
-constraints are defined in the \fBtcltest\fR package.  To add 
-constraints, you can call \fBtcltest::testConstraint\fR
-with the appropriate arguments in your own test file.
-.PP
-The following is a list of constraints defined in the \fBtcltest\fR package:
-.TP

-.TP
-\fItempNotMac\fR
-test can not be run on a Mac.  This flag is used

-.TP
-\fIunixCrash\fR
-test crashes if it's run on UNIX.  This flag is used to temporarily

-.TP
-\fIwinCrash\fR
-test crashes if it's run on Windows.  This flag is used to temporarily
-disable a test. 
-.TP
-\fImacCrash\fR
-test crashes if it's run on a Mac.  This flag is used to temporarily
-disable a test. 
-.TP
-\fIemptyTest\fR
-test is empty, and so not worth running, but it remains as a
-place-holder for a test to be written in the future.  This constraint
-always causes tests to be skipped.
-.TP
-\fIknownBug\fR
-test is known to fail and the bug is not yet fixed.  This constraint
-always causes tests to be skipped unless the user specifies otherwise.
-See the "Introduction" section for more details.
-.TP
-\fInonPortable\fR
-test can only be run in the master Tcl/Tk development environment.
-Some tests are inherently non-portable because they depend on things
-like word length, file system configuration, window manager, etc.
-These tests are only run in the main Tcl development directory where
-the configuration is well known.  This constraint always causes tests
-to be skipped unless the user specifies otherwise.  
-.TP
-\fIuserInteraction\fR
-test requires interaction from the user.  This constraint always
-causes tests to be skipped unless the user specifies otherwise.  
-.TP
-\fIinteractive\fR
-test can only be run in if the interpreter is in interactive mode 
-(when the global tcl_interactive variable is set to 1).
-.TP
-\fInonBlockFiles\fR
-test can only be run if platform supports setting files into
-nonblocking mode 
-.TP
-\fIasyncPipeClose\fR
-test can only be run if platform supports async flush and async close
-on a pipe 
-.TP

-test can only run if app has a working version of sprintf with respect
-to the "e" format of floating-point numbers.
-.TP
-\fIstdio\fR
-test can only be run if the current app can be spawned via a pipe
-.SH "RUNNING TEST FILES"
-Use the following command to run a test file that uses package
-tcltest:
-.DS
-<shell> <testFile> ?<option> ?<value>?? ...
-.DE
-Command line options include (tcltest accessor procs that
-correspond to each flag are listed at the end of each flag description
-in parenthesis): 
-.RS
-.TP
-\fB-help\fR
-display usage information.
-.TP
-\fB-singleproc <bool>\fR
-if <bool> is 0, run test files in separate interpreters.  if 1, source test
-files into the current intpreter. (tcltest::singleProcess)
-.TP
-\fB-verbose <levelList>\fR
-set the level of verbosity to a list containing 0 or more of "body",
-"pass", "skip", "start", and "error".  See the "Test output" section
-for an explanation of this option.  (tcltest::verbose)  
-.TP
-\fB-match <matchList>\fR
-only run tests that match one or more of the glob patterns in
-<matchList>.  (tcltest::match)
-.TP
-\fB-skip <skipList>\fR
-do not run tests that match one or more of the glob patterns in
-<skipList>.  (tcltest::skip)
-.TP
-\fB-file <globPatternList>\fR
-only source test files that match any of the items in
-<globPatternList> relative to tcltest::testsDirectory.  
-This option
-only makes sense if you are running tests using "all.tcl" as the
-<testFile> instead of running single test files directly.
-(tcltest::matchFiles) 
-.TP
-\fB-notfile <globPatternList>\fR
-source files except for those that match any of the items in
-<globPatternList> relative to tcltest::testsDirectory.
-This option
-only makes sense if you are running tests using "all.tcl" as the
-<testFile> instead of running single test files directly.
-(tcltest::skipFiles) 
-.TP
-\fB-relateddir <globPatternList>\fR
-only run tests in directories that match any of the items in
-<globPatternList> relative to tcltest::testsDirectory.  
-This option
-only makes sense if you are running tests using "all.tcl" as the
-<testFile> instead of running single test files directly.
-(tcltest::matchDirectories) 
-.TP
-\fB-asidefromdir <globPatternList>\fR
-run tests in directories except for those that match any of the items in
-<globPatternList> relative to tcltest::testsDirectory.
-This option
-only makes sense if you are running tests using "all.tcl" as the
-<testFile> instead of running single test files directly.
-(tcltest::skipDirectories) 
-.TP
-\fB-constraints <list>\fR
-tests with any constraints in <list> will not be skipped.  Note that
-elements of <list> must exactly match the existing constraints.  This
-is useful if you want to make sure that tests with a particular
-constraint are run (for example, if the tester wants to run all tests
-with the knownBug constraint).
-(tcltest::testConstraint)
-.TP
-\fB-limitconstraints <bool>\fR
-If the argument to this flag is 1, the test harness limits test runs
-to those tests that match the constraints listed by the -constraints
-flag. Use of this flag requires use of the -constraints flag.  The
-default value for this flag is 0 (false).  This is useful if you want
-to run \fBonly\fR those tests that match the constraints listed using
-the -constraints option.  A tester might want to do this if (for
-example) he were
-interested in running only those tests that are constrained to be
-unixOnly and no other tests.
-(tcltest::limitConstraints)
-.TP
-\fB-load <script>\fR
-will use the specified script to load the commands under test
-(tcltest::loadTestedCommands). The default is the empty
-script. See -loadfile below too. (tcltest::loadScript)
-.TP
-\fB-loadfile <scriptfile>\fR
-will use the contents of the named file to load the commands under
-test (tcltest::loadTestedCommands). See -load above too. The default
-is the empty script. (tcltest::loadFile)
-.TP
-\fB-tmpdir <directoryName>\fR
-put any temporary files (created with tcltest::makeFile and
-tcltest::makeDirectory) into the named directory.  The default
-location is tcltest::workingDirectory.  (tcltest::temporaryDirectory)
-.TP
-\fB-testdir <directoryName>\fR
-search the test suite to execute in the named directory.  The default
-location is tcltest::workingDirectory.  (tcltest::testsDirectory)
-.TP
-\fB-preservecore <level>\fR
-check for core files.  This flag is used to determine how much
-checking should be done for core files.  (tcltest::preserveCore)
-.TP
-\fB-debug <debugLevel>\fR
-print debug information to stdout.  This is used to debug code in the
-tcltest package.  (tcltest::debug)
-.TP
-\fB-outfile <filename>\fR 
-print output generated by the tcltest package to the named file.  This
-defaults to stdout.  Note that debug output always goes to stdout,
-regardless of this flag's setting.  (tcltest::outputFile)
-.TP
-\fB-errfile <filename>\fR
-print errors generated by the tcltest package to the named file.  This
-defaults to stderr.  (tcltest::errorFile)
-.RE
-.PP
-You can specify any of the above options on the command line or by
-defining an environment variable named TCLTEST_OPTIONS containing a
-list of options (e.g. "-debug 3 -verbose 'pass skip'").  This 
-environment variable is evaluated before the command line arguments.
-Options specified on the command line override those specified in 
-TCLTEST_OPTIONS. 
-.PP
-A second way to run tets is to start up a shell, load the
-\fBtcltest\fR package, and then source an appropriate test file or use
-the test command.  To use the options in interactive mode, set
-their corresponding tcltest namespace variables after loading the
-package.
-.PP
-See \fI"Test Constraints"\fR for a list of all built-in constraint names.
-.PP
-A final way to run tests would be to specify which test files to run
-within an \fIall.tcl\fR (or otherwise named) file.  This is the
-approach used by the Tcl test suite.  This file loads the tcltest
-package, sets the location of
-the test directory (tcltest::testsDirectory), and then calls the
-\fItcltest::runAllTests\fR proc, which determines which test
-files to run, how to run them, and calls tcltest::cleanupTests to
-determine the summary status of the test suite.  
-.PP
-A more elaborate \fIall.tcl\fR file might do some pre- and
-post-processing before sourcing 
-each .test file, use separate interpreters for each file, or handle
-complex directory structures.  
-For an example of an all.tcl file,
-please see the "Examples" section of this document.
-.SH "TEST OUTPUT"
-After all specified test files are run, the number of tests
-passed, skipped, and failed is printed to
-\fBtcltest::outputChannel\fR.  Aside from this 
-statistical information, output can be controlled on a per-test basis
-by the \fBtcltest::verbose\fR variable.
-.PP
-\fBtcltest::verbose\fR can be set to any combination of "body", 
-"skip", "pass", "start", or "error".  The default value of
-\fBtcltest::verbose\fR is "body".  If "body"  is present, then the
-entire body of the test is printed for each failed test, otherwise
-only the test's name, desired output, and 
-actual output, are printed for each failed test.  If "pass" is present,
-then a line is printed for each passed test, otherwise no line is
-printed for passed tests.  If "skip" is present, then a line (containing
-the consraints that cause the test to be skipped) is printed for each
-skipped test, otherwise no line is printed for skipped tests.  If "start"
-is present, then a line is printed each time a new test starts.
-If "error" is present, then the content of errorInfo and errorCode (if
-they are defined) is printed for each test whose return code doesn't
-match its expected return code.
-.PP
-You can set \fBtcltest::verbose\fR either interactively (after the
-\fBtcltest\fR package has been loaded) or by using the command line
-argument \fB-verbose\fR, for example:
-.DS
-tclsh socket.test -verbose 'body pass skip'
-.DE
-.SH "CONTENTS OF A TEST FILE"
-Test files should begin by loading the \fBtcltest\fR package:
-.DS
-package require tcltest
-namespace import -force tcltest::*
-.DE
-Test files should end by cleaning up after themselves and calling
-\fBtcltest::cleanupTests\fR.  The \fBtcltest::cleanupTests\fR
-procedure prints statistics about the number of tests that passed,
-skipped, and failed, and removes all files that were created using the
-\fBtcltest::makeFile\fR and \fBtcltest::makeDirectory\fR procedures.
-.DS
-# Remove files created by these tests
-# Change to original working directory
-# Unset global arrays
-tcltest::cleanupTests
-return
-.DE
-When naming test files, file names should end with a .test extension.
-The names of test files that contain regression (or glass-box) tests
-should correspond to the Tcl or C code file that they are testing.
-For example, the test file for the C file "tclCmdAH.c" is "cmdAH.test".  
-.SH "SELECTING TESTS FOR EXECUTION"
-.PP
-Normally, all the tests in a file are run whenever the file is
-sourced.  An individual test will be skipped if one of the following
-conditions is met:
-.IP [1]
-the \fIname\fR of the tests does not match (using glob style matching)
-one or more elements in the \fBtcltest::match\fR variable
-.IP [2]
-the \fIname\fR of the tests matches (using glob style matching) one or
-more elements in the \fBtcltest::skip\fR variable 
-.IP [3]
-the \fIconstraints\fR argument to the \fBtcltest::test\fR call, if
-given, contains one or more false elements. 
-.PP
-You can set \fBtcltest::match\fR and/or \fBtcltest::skip\fR
-either interactively (after the \fBtcltest\fR package has been
-sourced), or by using the command line arguments \fB-match\fR and
-\fB-skip\fR, for example: 
-.PP
-.CS
-tclsh info.test -match '*-5.* *-7.*' -skip '*-7.1*'
-.CE
-.PP
-Be sure to use the proper quoting convention so that your shell does
-not perform the glob substitution on the match or skip patterns you
-specify.
-.PP
-Predefined constraints (e.g. \fIknownBug\fR and \fInonPortable\fR) can be
-overridden either interactively (after the \fBtcltest\fR package has been
-sourced) by setting the proper constraint
-or by using the \fB-constraints\fR command line option with the name of the
-constraint in the argument.  The following example shows how to run
-tests that are constrained by the \fIknownBug\fR and \fInonPortable\fR
-restrictions:
-.PP
-.CS
-tclsh all.tcl -constraints "knownBug nonPortable"
-.CE
-.PP
-See the \fI"Constraints"\fR section for information about using
-built-in constraints and adding new ones.
-.PP
-When tests are run from within an 'all.tcl' file, all files with a
-'.test' extension are normally run.  An individual test file will be
-skipped if one of the following conditions is met:
-.IP [1]
-the \fIname\fR of the test files does not match (using glob style matching)
-one or more elements in the \fBtcltest::matchFiles\fR variable
-.IP [2]
-the \fIname\fR of the test file matches (using glob style matching) one or
-more elements in the \fBtcltest::skipFiles\fR variable 
-.PP
-You can set \fBtcltest::matchFiles\fR and/or \fBtcltest::skipFiles\fR
-either interactively (after the \fBtcltest\fR package has been
-sourced), or by using the command line arguments \fB-file\fR and
-\fB-notfile\fR, for example: 
-.PP
-.CS
-tclsh info.test -file 'unix*.test' -notfile 'unixNotfy.test'
-.CE
-.PP
-Additionally, if tests are run from within an 'all.tcl' containing a
-call to \fBtcltest::runAllTests\fR, any subdirectory of
-\fItcltest::testsDirectory\fR containing an 'all.tcl' file will also
-be run.  Individual test subdirectories will be skipped if one of the
-following conditions is met:
-.IP [1]
-the \fIname\fR of the directory does not match (using glob style matching)
-one or more elements in the \fBtcltest::matchDirectories\fR variable
-.IP [2]
-the \fIname\fR of the directory matches (using glob style matching) one or

-.PP
-You can set \fBtcltest::matchDirectories\fR and/or \fBtcltest::skipDirectories\fR
-either interactively (after the \fBtcltest\fR package has been

-.SH "HOW TO CUSTOMIZE THE TEST HARNESS"
-To create your own custom test harness, create a .tcl file that contains your
-namespace.  Within this file, require package \fBtcltest\fR.  Commands

-\fBtcltest::PrintUsageInfoHook\fP
-print additional usage information specific to your situation.
-.TP
-\fBtcltest::processCmdLineArgsFlagHook\fP
-tell the test harness about additional flags that you want it to understand.

-To add new built-in
-constraints to the test harness, define your own version of
-\fBtcltest::initConstraintsHook\fR. 
-Within your proc, you can add to the \fBtcltest::testConstraints\fR array.
-For example:
-.DS
-proc tcltest::initConstraintsHook {} {
-    set tcltest::testConstraints(win95Or98) \\
-            [expr {$tcltest::testConstraints(95) || \\
-            $tcltest::testConstraints(98)}]
-}

-.PP
-Finally, if you want to add additional cleanup code to your harness
-you can define your own \fBtcltest::cleanupTestsHook\fR.  For example:
-.DS
-proc tcltest::cleanupTestsHook {} {
-    # Add your cleanup code here

-.SH "KNOWN ISSUES"
-There are two known issues related to nested test commands.  
-The first issue relates to the stack level in which test scripts are
-executed.  Tests nested within other tests may be executed at the same
-stack level as the outermost test.  For example, in the following test
-code: 
-.DS
-test level-1.1 {level 1} {
-    -body {
-        test level-2.1 {level 2} {
-        }
-    }
-}
-.DE
-any script executed in level-2.1 may be executed at the same stack
-level as the script defined for level-1.1.  
-.PP
-In addition, while two
-test commands have been run, results will only be reported for tests
-at the same level as test level-1.1.  However, test results for all
-tests run prior to level-1.1 will be available when test level-2.1
-runs.  What this means is that if you try to access the test results
-for test level-2.1, it will may say that 'm' tests have run, 'n' tests
-have been skipped, 'o' tests have passed and 'p' tests have failed,
-where 'm', 'n', 'o', and 'p' refer to tests that were run at the same
-test level as test level-1.1. 
-.PP
-Implementation of output and error comparison in the test command
-depends on usage of puts in your application code.  Output is
-intercepted by redefining the puts command while the defined test
-script is being run.  Errors thrown by C procedures or printed
-directly from C applications will not be caught by the test command.
-Therefore, usage of expect_out and expect_err in the test command is
-useful only for pure Tcl applications that use the puts command for
-output.

 #
-# Check Constraintsuration information that will determine which tests
-# to run.  To do this, create an array ::tcltest::testConstraints.  Each
-# element has a 0 or 1 value.  If the element is "true" then tests
-# with that constraint will be run, otherwise tests with that constraint
-# will be skipped.  See the tcltest man page for the list of built-in
-# constraints defined in this procedure.
+#	Set or return the verbosity level (tcltest::verbose) for tests.  This
+#       determines what gets printed to the screen and when, with regard to the
+#       running of the tests.  The proc does not check for invalid values.  It
+#       assumes that a string that doesn't match its predefined keywords
+#       is a string containing letter-specified verbosity levels.
 #
 # Arguments:
-#	none
+#	A string containing any combination of 'pbste' or a list of keywords
