The OTA (Open Tools API) Template is a project which contains the code associated with the various blog posts and the Open Tools API book.
The expert/wizard contains example code referenced in the blog post and book which provides an auto save feature for the IDE along with a project wizard which can create the framework for a new Open Tool API project so that you can concentrate on simply coding the functionality of the expert/wizard rather than remembering the code to create various wizard/notifier interfaces.
You can download the DLL and BPL versions of this expert/wizard and all the code for 2009, 2010, XE, XE2, XE7 and XE10.
Please note there are only builds of this OTA project for RAD Studio 2009, 2010, XE, XE2, XE7 and XE10 due to the restrictions described in Open Tools API page.
