I couldn't find the syntax understood by the CVS reader for tags.
I tried:
":pserver:anonymous@dev.eclipse.org:/cvsroot/eclipse,org.eclipse.ant.core;v20110511"
and
":pserver:anonymous@dev.eclipse.org:/cvsroot/eclipse,org.eclipse.ant.core,tag=v20110511"
and other variations, but it doesn't work.
Is it possible to specify a tag in a CVS URI? What is the correct syntax?
