Sharing files across directories

[Matt Lyon]

Hi,

Is there a way to share a single source file across multiple directories in 
CVS, so that if it gets committed/merged in one directory the update registers 
in both locations?  I know that VSS has this concept, and was wondering if CVS 
offers any sort of similar functionality. I was thinking that perhaps this 
could be achieved with some symlink trickery on the server-side?
