For our product we have several repos that all need to be branched when releasing a stable version. Manually doing this takes a lot of time and because of that I created an ant-script that does this. There are four main public targets and four main private targets:

A public target to create branches and a private to create one branch.
A public target to create tags and a private to create one tag.
A public target to delete branches and a private to delete one branch.
A public target to delete tags and a private to delete one tag.

Important parameters that need to be defined (can be done using ant-form, in a properties file or in the main ant file):

cvsdude.repository.branch.name : Name of the branch to create or delete in each of the repositories.
cvsdude.repository.tag.name : Name of the tag to create or delete in each of the repositories.
cvsdude.repository.user : Username for credentials repository.
cvsdude.repository.passwd : Password for credentials repository.
repos : Comma seperated list of the url's of repositories.

I guess that some things can be made more generic and put in macros as lot of logic is duplicated.... But this should get you going.

The libraries you need are svnant and ant-contrib.
