Installing Subclipse

To install Subclipse:

1. From Eclipse, go to "Help -> Install New Software"
2. Add a site with URL subclipse.tigris.org/update_1.6.x
3. Next, you have to make a decision whether to use JavaHL or SVNKit as the SVN connection library.
   1. JavaHL uses the native SVN libraries (and will require SVN and/or its library files to be installed on your system, and also additional command line options to eclipse startup script).
   2. SVNKit re-implements all the SVN connection related functionality in Pure Java.
   3. Basically JavaHL is more difficult to setup & maintain, but uses same code as native SVN client for SVN connectivity. Therefore likely to have latest & greatest features & fixes.
   4. SVNKit is easy to setup & maintain, but may not always have the latest & greatest features & fixes.
   5. Generally I have found SVNKit to be adequate.
   6. Eclipse marks JavaHL as "Required". Actually it is not required. You just need either JavaHL OR SVNKit.
4. The above was the most tricky part. Just click through the menus and it will download and install.
