svn externals

This is the subversion space trick for sharing one stylesheet across numerous projects in source control or doing a similar stunt to keep content referenced by multiple projects in one place in source control.

 
 

Addendum 10/28/2015: Use TortoiseSVN to add a new external at a folder that has externals intergrated already like so:

1. right-click on a folder and pick "Properties" under "TortoiseSVN"
2. select the svn:externals line item and click "Edit..."
3. click the "New..." button at the list of externals
