The summary basically says it all. This lets you use Subversion with Matlab. I didn't see any other implementation on this, so I wrote this simple version for my group. Put this file in the ../toolbox/matlab/verctrl/ directory, overwriting the existing file there with the same name. Then go to matlab preferences, click on source control, and change it to "custom." Now in a matlab editor, you can use the menu items under File-Source Control.
Subversion doesn't use the "lock" concept, so that isn't implemented here. I also didn't implement the "undo checkout" feature. However, Zheng Li implemented that feature, and it is included in the "customverctr.m" file. My old version is "customverctr_noundo.m".
Improvements or comments are welcome.
