To tag the version you currently have checked out, go into the root 
directory of the module (e.g., Numeric) and AFTER CHECKING IN ALL 

cvs tag [-c] <symbolic-tag>

where <symbolic-tag> is the tag name. This will apply <symbolic-tag> to the 
current revision of each file that you have checked out. It is important to 
note that the tag is applied to the repository so it is essential that you 
check in all modified files and resolve conflicts BEFORE tagging the 
repository. The -c flag tells cvs to check that all files in the local 
directory are unmodified and warns you if they are not.

The restrictions on the tag name are not well-documented, but if they match 
the regular expression


they will work (i.e., matching this regex is a sufficient but perhaps not 
necessary condition). Tags that begin with [0-9] or that contain [ \t.,;:] 
will not work.

If you want to go back and tag old releases without checking them out, then 
if there is a target date that you can use to identify the version (e.g., a 
release date), you can run

cvs rtag -D <date> <symbolic-tag> <module>

Where <date> is the date. For format, the following excerpt from the 
Cederqvist manual may help:

This command will tag all files in <module> at the latest revision on or 
before <date> with tag <symbolic-tag>.

I hope this is helpful to you.
