[news.eclipse.platform] Creating custom .project / .classpath file?

[pnakat@xxxxxxxxx (Prajakta)]

Hi,

I am creating a custom defined project type ABC which has its own nature 
ABCNature. I want to save a few files/paths related to the new project 
(like source folder, output folder in case of a Java Project) in a special 
project / .classpath file say .abcProject file. This file should contain 
it's own classPathEntries (CPE's like java .classpath) file.

For example, the .abcProject file would contain an entry for repository as 
:

<repository>
<path> C:\abc\xyz\qwert.xml</path>
<active>yes</active>
</repository>

OR

type = "repository" path = "C:\abc\xyz\qwert.xml"
in .classpath file.

Can someone please guide me if this is possible in Eclipse? If yes, how do 
i proceed with creating a special .project file and define tags in it?

Thanks,
Prajakta
