Creating a simple tag in SVN
Answer:
In SVN, a tag is a “snapshot” of a project in time. By creating a tag of a project, this allow you to easily reference a particular version sometimes later.
To create a tag, use svn copy:
# svn copy http://example.com/svn/repos/demo/trunk \
http://example.com/svn/repos/demo/tags/release-1.0.0 \
-m "Tagging the 1.0.0 release of the 'demo' project."
Committed revision 124.
