When you are coding in a team enviroment it's good to have the subversion properties in your files, that way any other developer can see quickly who made the last changes and when.

You can add the following lines at the bottom of your code:

//  $LastChangedDate: $
//  $Revision: $
//  $LastChangedBy: $
//  $Id: $
And when you perform your svn commit will be automatically populated something like this:
//  $LastChangedDate: 2012-02-11 18:24:39 -0500 (Sat, 11 Feb 2012) $
//  $Revision: 61 $
//  $LastChangedBy: adriansky $
//  $Id: Heap.java 61 2012-02-11 23:24:39Z adriansky $
Also you need to set the SVN properties for that file. The Properties that you need are the following:
  • svn:eol-style  —> LF
  • svn:keywords —> LastChangedDate Revision LastChangedBy Id
If you are using Eclipse you can edit it following this steps:
  1. right click file you want to add svn properties
  2. Menu team > set properties (image below)
  3. Select the Property name from the combobox (image below)
  4. Add the text property in the text box (image below)
  5. You can also use files to avoid all the typing every time. right click and 'save as…' to <svn-keywords> and <svn-eol-property>.
  6. Commit and you are all set.
