+ *Fill forms automatically
+ *
+ * Extension that saves form data and  fills forms with previously saved data
+ *
+ * To use this extension save this script as $HOME/.local/share/dwb/extensions/formfiller 
+ * and load it with a userscript in $HOME/.config/dwb/userscripts/, e.g. 
+ *
+ * ------------------------------------------------------------------------------

+ * ------------------------------------------------------------------------------
+ *
+ *
+ * Configuration options:
+ *
+ * formData       : A path to a file where formdata will be saved, the default
+ *                  path is $XDG_CONFIG_HOME/dwb/forms
+ *
+ * scGetForm      : Shortcut that gets and saves form data, the default value is
+ *                  'efg'
+ *
+ * scFillForm     : Shortcut that fills a form, the default value is 'eff'
+ *
+ * useGPG         : Whether to use gpg2 to encrypt the formData file with a
+ *                  password.
+ *
+ * GPGOptEncrypt : Additional options that will be passed to gpg2 for
+ *                 encryption, the default gpg2 options are:
+ *                 --passphrase <password> --batch --no-tty --yes -c --output <formData>
+ *                 default value: ""
+ *
+ * GPGOptDecrypt : Additional options that will be passed to gpg2 for
+ *                 decryption, the default gpg2 options are 
+ *                 --passphrase <password> --batch --no-tty --yes -d <formData>
+ *                 default value: ""
+ *
+ * keepPassword  : Whether to save the gpg password in memory, if set to false the
+ *                 user will be prompted for the password every time a form
+ *                 is filled or new data is saved, default value: true
+ *
+ * keepFormdata  : If useGPG is enabled and this value is set to true the
+ *                 complete formdata will be kept in memory, if set to false
+ *                 gpg2 will be called every time a form is filled, default
+ *                 value: false.
