##                   VERSIONING SEMANTICS
##
## Version consistes of <major> . <minor> . <release> - <revision>
## Where:
##    major   : Production (0 = pre-production)
##    minor   : 0-7 = Production minor, 8 = Alpha, 9 = Beta
##    release : Release tag
##    revision: Release revision - 0 = development (cutting edge). 
##
## Usage:
##     Default - VERSION_REVISION is set to the value defined here
##     Env variable PRODUCER_VERSION_REVISION overrides default    
##           e.g.:
##               % setenv PRODUCER_VERSION_REVISION 5
##               % make version
##     Command line overrides env variable
##               % make VERSION_REVISION=
