|
|---|
| 9 | <h3>Description</h3>
|
|---|
| 10 | <p>Generates an XML-formatted report file of the changes between two tags or dates recorded in a
|
|---|
| 11 | <a href="http://www.cvshome.org/" target="_top">CVS</a> repository. </p>
|
|---|
| 12 | <p><b>Important:</b> This task needs "cvs" on the path. If it isn't, you will get
|
|---|
| 13 | an error (such as error 2 on windows). If <code><cvs></code> doesn't work, try to execute <code>cvs.exe</code>
|
|---|
| 14 | from the command line in the target directory in which you are working.
