The following example accepts the following arguments and displays their values :
- A flag named 'boolean_flag', which also has the 'bf' alias
- An optional string parameter, named 'string_parameter' (or 'sp') with a default value of
"this is the default value".
- An unlimiter number of strings or filenames.
Since no "name=" attribute is specified on the <command> tag of the parameter definitions, it will be
set to the name of the current script, without its extension.
Note also that the usage text contains some PHP code, which displays the current date and time.
You can invoke the script using the reserved parameters -help, -usage or -topics ; but you can also
specify the special parameters beginning with "--".
