Re: Special support for tags and branches

In Subcommander, the user has to write the tags- and branches- URL, in
addition to the trunk URL. (Or click on a 'standard project layout' button
to choose the common tags/, branches/ and trunk/ layout.) Have you
received any feedback on the need to write in the three URLs? Is that why
you put in a 'standard project layout'?

How do you Martin, as a Subcommander developer, view my suggestion that
Subversion should standardize on using properties to locate the tags- and
branches- directories, and to use properties to mark a tag (in the tags
directory) and a branch (in the branch) directory?

And what do you think of making special commands in Subversion for tagging
and branching, which utilizes the properties.

By the way, Subcommander defines a 'project' in the exact same way. (But
Subcommander also puts working copies of the 'branchpoint' into the
project definition.)
