The oik base plugin provides a simple admin user interface where you can enter some often included key information and many shortcodes to allow you to embed this information within your website.
It also provides you the ability to define the CSS information to format the information the way you want. [bw_editcss]
Each of the shortcodes that you can use may be included in titles, page and post content and widgets.
Some of the shortcodes also allow you to enter your own XHTML markup. This enables you to create nicely formatted content with the minimum of effort.
When editing a page or post in Visual mode you can click on a choice of buttons to display a dialog from which to select the shortcode you need. When using the HTML editor you use the  quicktag button.
The buttons are not available for Text Widgets and other fields, but you can copy and paste the generated shortcode as and when necessary.
The version on oik-plugins and GitHub features the bleeding edge changes that are being tested before being released to the WordPress repository. New features appear here first. The version on WordPress.org is the latest stable version.
