I am ready to create a TAG today, finding the DOC found that Subversion's BRANCHES and TAGs are actually implemented with the directory, and it is very different from CVS. It is too uncomfortable. It is also a directory, even in the project root catalog. A tag directory, then the whole root directory COPY to TAG. A total of 3MB projects actually let the hard drive will not stop reading. After a long time, I think that Copy is recuing ~~~~~~~~~ Tag returns to be copied, it is not to create a directory in the tag directory until the hard disk is exhausted.
Dizzy. Now I have a reservation attitude towards Subversion, or a good CVS, wait and see. Fortunately, I didn't put important things to the Subversion tube.
