+
+# Experimental hooks are available to run tests remotely on machines that
+# are able to run curl but are unable to run the test harness.
+# The following sections need to be modified:
+#
+#  $HOSTIP, $HOST6IP - Set to the address of the host running the test suite
+#  $CLIENTIP, $CLIENT6IP - Set to the address of the host running curl
+#  runclient, runclientoutput - Modify to copy all the files in the log/
+#    directory to the system running curl, run the given command remotely
+#    and save the return code or returned stdout (respectively), then
+#    copy all the files from the remote system's log/ directory back to
+#    the host running the test suite.  This can be done a few ways, such
+#    as using scp & ssh, rsync & telnet, or using a NFS shared directory
+#    and ssh.
+#
+# 'make && make test' needs to be done on both machines before making the
+# above changes and running runtests.pl manually.  In the shared NFS case,
+# the contents of the tests/server/ directory must be from the host
+# running the test suite, while the rest must be from the host running curl.
+#
+# Note that even with these changes a number of tests will still fail (mainly
+# to do with cookies, those that set environment variables, or those that
+# do more than touch the file system in a <precheck> or <postcheck>
+# section). These can be added to the $TESTCASES line below,
+# e.g. $TESTCASES="!8 !31 !63 !cookies..."
+#
+# Finally, to properly support -g and -n, checktestcmd needs to change
+# to check the remote system's PATH, and the places in the code where
+# the curl binary is read directly to determine its type also need to be
+# fixed. As long as the -g option is never given, and the -n is always
+# given, this won't be a problem.
+
+
+# These should be the only variables that might be needed to get edited:
