terminology question: modules, directories, authors

[Richard Cyganiak]

Hi,

I'm a developer for a CVS related project (http://statcvs.sf.net) and have
some questions on the accurate use of some terminology:

When do you call something a module, and when do you call it a directory?

Which term do you suggest for referring to the users who commit to a
repository? Authors? Users? Developers?

Thanks,
Richard
