Where: type_info is either 'string', 'number', 'boolean', 'password' or 'choice(ch1,ch2,ch3,...)' If the marker 'required' is included after the type_info, the parameter will has some visually distinctive marking in the UI. 'description' is a short sentence describing the parameter 'choice' is rendered as a drop-down list. The first parameter in the list will be activated by default 'boolean' is rendered as a checkbox. The resulting parameter will be either 'true' or 'false' 'string' allows any characters 'number' allows only numbers 'password' is rendered as a password field (the characters are replaced with *'s when being types. This parameter is not passed through to the plugin. It is instead inserted directly into the password cache keyed on the instance name. The value of the parameter 'bindPWPrompt' (see example below) is set to the key. In addition to the configurable parameters, the following magic parameters may be defined: HELP_TOKEN;helptoken - a pointer to the online manual section for this plugin HELP_TEXT;helptext - a general help string describing the plugin For example: "username;string;The username you wish to login as" "bindPWPrompt;password;Enter password to bind as above user with" "algorithm;choice(RSA,DSA);Which algorithm do you want to use" "enable;boolean;Do you want to run this plugin" "port;number;Which port number do you want to use"
