+# Example test:
+# name: a-test
+# description:
+# a test to show how tests are done
+# arguments: !-x!-f!
+# stdin:
+# echo -n *
+# false
+# expected-stdout: !
+# *
+# expected-stderr:
+# + echo -n *
+# + false
+# expected-exit: 1
+# ---
+# This runs the test-program (eg, mksh) with the arguments -x and -f,
+# standard input is a file containing "echo hi*\nfalse\n". The program
+# is expected to produce "hi*" (no trailing newline) on standard output,
+# "+ echo hi*\n+false\n" on standard error, and an exit code of 1.
+#
+#
+# Format of test files:
+# - blank lines and lines starting with # are ignored
+# - a test file contains a series of tests
+# - a test is a series of tag:value pairs ended with a "---" line
+# (leading/trailing spaces are stripped from the first line of value)
+# - test tags are:
+# Tag Flag Description
+# ----- ---- -----------
+# name r The name of the test; should be unique
+# description m What test does
+# arguments M Arguments to pass to the program;
+# default is no arguments.
+# script m Value is written to a file which
+# is passed as an argument to the program
+# (after the arguments arguments)
+# stdin m Value is written to a file which is
+# used as standard-input for the program;
+# default is to use /dev/null.
+# perl-setup m Value is a perl script which is executed
+# just before the test is run. Try to
+# avoid using this...
+# perl-cleanup m Value is a perl script which is executed
+# just after the test is run. Try to
+# avoid using this...
+# env-setup M Value is a list of NAME=VALUE elements
+# which are put in the environment before
+# the test is run. If the =VALUE is
+# missing, NAME is removed from the
+# environment. Programs are run with
+# the following minimal environment:
+# HOME, LD_LIBRARY_PATH, LOCPATH,
+# LOGNAME, PATH, SHELL, UNIXMODE,
+# UNIXROOT, USER
+# (values taken from the environment of
+# the test harness).
+# CYGWIN is set to nodosfilewarning.
+# ENV is set to /nonexistant.
+# __progname is set to the -p argument.
+# __perlname is set to $^X (perlexe).
+# @utflocale@ is substituted from -U.
+# file-setup mps Used to create files, directories
+# and symlinks. First word is either
+# file, dir or symlink; second word is
+# permissions; this is followed by a
+# quoted word that is the name of the
+# file; the end-quote should be followed
+# by a newline, then the file data
+# (if any). The first word may be
+# preceded by a ! to strip the trailing
+# newline in a symlink.
+# file-result mps Used to verify a file, symlink or
+# directory is created correctly.
+# The first word is either
+# file, dir or symlink; second word is
+# expected permissions; third word
+# is user-id; fourth is group-id;
+# fifth is "exact" or "pattern"
+# indicating whether the file contents
+# which follow is to be matched exactly
+# or if it is a regular expression.
+# The fifth argument is the quoted name
+# of the file that should be created.
+# The end-quote should be followed
+# by a newline, then the file data
+# (if any). The first word may be
+# preceded by a ! to strip the trailing
+# newline in the file contents.
+# The permissions, user and group fields
+# may be * meaning accept any value.
+# time-limit Time limit - the program is sent a
+# SIGKILL N seconds. Default is no
+# limit.
+# expected-fail 'yes' if the test is expected to fail.
+# expected-exit expected exit code. Can be a number,
+# or a C expression using the variables
+# e, s and w (exit code, termination
+# signal, and status code).
+# expected-stdout m What the test should generate on stdout;
+# default is to expect no output.
+# expected-stdout-pattern m A perl pattern which matches the
+# expected output.
+# expected-stderr m What the test should generate on stderr;
+# default is to expect no output.
+# expected-stderr-pattern m A perl pattern which matches the
+# expected standard error.
+# category m Specify a comma separated list of
+# 'categories' of program that the test
+# is to be run for. A category can be
+# negated by prefixing the name with a !.
+# The idea is that some tests in a
+# test suite may apply to a particular
+# program version and shouldn't be run
+# on other versions. The category(s) of
+# the program being tested can be
+# specified on the command line.
+# One category os:XXX is predefined
+# (XXX is the operating system name,
+# eg, linux, dec_osf).
+# need-ctty 'yes' if the test needs a ctty, run
+# with -C regress:no-ctty to disable.
+# Flag meanings:
+# r tag is required (eg, a test must have a name tag).
+# m value can be multiple lines. Lines must be prefixed with
+# a tab. If the value part of the initial tag:value line is
+# - empty: the initial blank line is stripped.
+# - a lone !: the last newline in the value is stripped;
+# M value can be multiple lines (prefixed by a tab) and consists
+# of multiple fields, delimited by a field separator character.
+# The value must start and end with the f-s-c.
+# p tag takes parameters (used with m).
+# s tag can be used several times.
+

+ -s s Read tests from file s; if s is a directory, it is recursively
+ scaned for test files (which end in .t).
+ -T dir Use dir instead of /tmp to hold temporary files
+ -t t Use t as default time limit for tests (default is unlimited)
+ -U lcl Use lcl as UTF-8 locale (e.g. C.UTF-8) instead of the default
+ -v Verbose mode: print reason test failed.
+ name specifies the name of the test(s) to run; if none are
