Client parameters are assumed to be

one or more instances of bracketed pairs:

e.g "[...][...]...".

The bracket content in turn is assumed to be a
|
|
comma separated list of <name>=<value> pairs.
|
|
e.g. x=y,z=,a=b.
|
|
If the same parameter is specifed more than once,

then the first occurrence is used; this is so that
|
|
is possible to forcibly override user specified
|
|
parameters by prefixing.
|
|
IMPORTANT: client parameter string is assumed to
|
|
have blanks compress out.
