Package naming scheme

Slicer-<MAJOR_VERSION>.<MINOR_VERSION>.<BUILD_VERSION>-<[svn<REV>[-dirty]|rc{1|2|3...}|(null)]>-<DATE>-<ARCH>-<PLATFORM>

We can distinguish between two stages:

• Development: The suffix svn<REV> allows to identify the revision associated with the current package. The -dirty prefix indicates if the package has been generated from a locally modified source tree.

• Release: The optional suffix rc{1|2|3|...} allows to identify the different release candidates leading to a final release.

Notes/problems:

- no date to differentiate release candidates from each others 
- release packages are not nightly builds, but manual builds
