CVS and EA5 - Noob questions

[Wargfang]

Hi all.

Im a new EA user (and a pretty happy one).

Ive decided to link my EA and its models (mostly use cases and class diagrams at the moment). There isnt (or I havent found) extensive doco on this. So can someone confirm the following :-

- The lowest level element I can check in/out is a package
- EA does this via effectively XML export to CVS and then XML import
- Searching the forums Ive seen some warnings about stuff getting lost. Is this true (shudder)

Any advice on using CVS...is checking in at package level generally accepted as being appropriate ?

Thanks in advance.
