Hi,

what's the best way to implement the $VERSION number in module distributions with multiple packages? I looked in the code of several CPAN modules and found different strategies:

• define $VERSION only in the main class, all others have no version number
• define $VERSION in all packages, sync them in all files before release
• define $VERSION in all packages, but these are internal version numbers (update only when package changes)
• use an import function in a base package so that inherited packages use this $VERSION
• use CVS/SVN revision numbers

How would you do this? Thanks!

Update: Changed title.
