/*
* The options that are listed below may be specified in the url if the allowParameters option is
* true. To do so first append a question mark ? to the end of the url. Next, specify the option
* name followed by an equal sign = and then the value; for example, option=value. Multiple options
* are specified by separating them with an ampersand &; for example, option1=value1&option2=value2.
* Enter %26 to specify an ampersand & character in the url, %3D for an equal = sign.
*
* The username option is an exception and is always allowed to be specified in the url, but whether
* or not it is actually used depends on other options.
*
* All parameters may be specified by their regular name or by a short form; the short form that can
* be used is specified in parenthesis at the beginning of the parameter's description. The general
* naming convention for the short name is to use the first letter of each word comprising the name.
* Be aware of conflicts though, such as backgroundColor (bc) and borderColor (bdc). Whether the
* full or short name is used specify the parameter name in lowercase.
*
* Examples
*
* scrobblersig.php
* scrobblersig.php?fontsize=24
* scrobblersig.php?labelcolor=aa0000&trackcolor=a9b200
* scrobblersig.php?fs=24
* scrobblersig.php?lc=aa0000&tc=a9b200

* - <time> Outputs the time according to the timeFormat option
* - <zone> Outputs the timezone according to the timeZoneOffset and timeZoneLabel options. The
* timeZoneLabel is output instead of the timeZoneOffset if it is present.

*
* "This song was played at <time> <zone> on <date>"
