java - Eclipse p2 : Difference between category.xml and site.xml -

-

p2 repository creation ant tasks eclipse.publish.featuresandbundles seem take site.xml or category.xml file specifies category information.

i see contents of site.xml , category.xml eclipse generates same right down tags.

so difference between two?

edit - clear :
additions/subtractions present in category.xml differentiate site.xml apart filenames?

the main difference between site.xml provides information update site , other repo information can structured, , part of update site, of 3.4 has been replaced content.xml , artifacts.xml

in categories xml file describing categories, can consumed during p2 build , produces categories seen in help>install new software dialog. again p2, categories.xml can replaced child repo in composite repo containing information expect.
