2009-10-19 Rolling back a change

Suppose you inadvertently made changes in some files some time back. You can examine revisions of files with

 $ svn log ccsds.h

You see that the previous revision was 205 and that it was correct. With an SVN merge, you can make that old revision the current revision:

 $ svn merge -r HEAD:205 ccsds.h

Check in your file and you're done!
