From Aptana Development

This extension point allows the user to contribute samples to the "samples" pane.

* The PNG image (16x16) is the image to display next to the library name.
* The "samples" directory is the root directory under which all samples live (note, no nesting of samples).
* The "infoFile" is an HTML index file which can be used to provide additional information about the samples.
* The preview handler can be left alone...that indicates we've created a special class that allows the user to preview a HTML sample without needing to import it as a project.

The "includePath" sub element allows us to copy common code into a project when creating or previewing the sample, thus preventing use from needing to include the library in every sample.

Example

<extension
       point="com.aptana.ide.samples.samplespath">
       <samplesinfo
           directory="samples"
           iconFile="icons/library.png"
           infoFile="samples/index.html"
           name="LibraryName Samples"
           previewHandler="com.aptana.ide.documentation.samples.AjaxSamplesPreviewHandler">
           <include path="libraries/lib"/>                   
       </samplesinfo>
</extension>
