+.TH runtests.pl 1 "2 Feb 2010" "Curl 7.69.0" "runtests"
 .SH NAME
 runtests.pl \- run one or more test cases
 .SH SYNOPSIS
-.B runtests.pl [options] [test number] [!test number] [key word] [!key word]
+.B runtests.pl [options] [tests]
 .SH DESCRIPTION
 \fIruntests.pl\fP runs one, several or all the existing test cases in curl's
 test suite. It is often called from the root Makefile of the curl package with
 \&'make test'.
-.SH "TEST NUMBER"
-If no test case number is given, all existing tests that the script can find
-will be considered for running. You can specify single test cases to run,
-space-separated, like "1 3 5 7 11", and you can specify a range like "45 to
-67". You can also specify only the tests you don't want to run by listing
-the numbers with a leading exclamation point, like "!66".
-.P
-It is also possible to specify tests to skip based on a key word describing
-the test. These are specified with a leading exclamation point and the
-key word or phrase, like "!HTTP NTLM auth".  Likewise, tests to run can
-be specified simply by specifying the unadorned key words, like "FTPS".
-Remember that the exclamation marks and spaces will need to be quoted somehow
-when entered at many command shells.
+.SH "TESTS"
+Specify which test(s) to run by specifying test numbers or keywords.
+
+If no test number or keyword is given, all existing tests that the script can
+find will be considered for running. You can specify single test cases to run
+by specifying test numbers space-separated, like "1 3 5 7 11", and you can
+specify a range of tests like "45 to 67".
+
+Specify tests to not run with a leading exclamation point, like "!66", which
+runs all available tests except number 66.
+
+Prefix a test number with a tilde (~) to still run it, but ignore the results.
+
+It is also possible to specify tests based on a keyword describing the test(s)
+to run, like "FTPS". The keywords are strings used in the indiviual tests.
+
+You can also specify keywords with a leading exclamation point and the keyword
+or phrase, like "!HTTP NTLM auth" to run all tests \fBexcept\fP those using
+this keyword. Remember that the exclamation marks and spaces will need to be
+quoted somehow when entered at many command shells.
+
+Prefix a keyword with a tilde (~) to still run it, but ignore the results.
 .SH OPTIONS
 .IP "-a"
 Continue running the rest of the test cases even if one test fails. By
