Plugin not visible in Ckeditor Profiles.

After enabling the module, and clearing cache as well. Plugin named: CKEditor Accordion - A plugin to easily create accordions, is not visible under the Editor appearance fieldset and under the Plugin title. This was due to path mismatch mention under the Line number 15 in ckeditor_accordion.module. During debugging the path looks like below.

/sites/all/modules/ckeditor_accordion/plugins/accordion/

Note here the beginning forward slash which means / -> root, however it should ./ -> This directory as root. Following is the correct one.

./sites/all/modules/ckeditor_accordion/plugins/accordion/
