documented the %-variables

Set 'option=no-output' to prevent the test script to slap on the --output

argument that directs the output to a file. The --output is also not added if

the client/stdout section is used.

Available substitute variables include:

%HOSTIP    - IP address of the host running this test

%HOSTPORT  - Port number of the HTTP server

%HTTPSPORT - Port number of the HTTPS server

%FTPPORT   - Port number of the FTP server

%FTPSPORT  - Port number of the FTPS server

%SRCDIR    - Full path to the source dir

%PWD       - Current directory

</command>

<file name="log/filename">

this creates the named file with this content before the test case is run
