##                   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=

## NOTE - Semantics for the use of ARCH, ARCHARGS, and ARCHINST parameters
## ARCH     - must be defined if the OS supports both 64 and 32 bit 
##           architectures may remain undefined if it does not.
## ARCHARGS - Compiler directives to indicate for which architecture 
##           to build for
## ARCHINST - Installation target directory.  Define if the OS supports 
##           more than one architecture (32 and 64).
##              for ARCH=32 - define ARCHINST only if the system uses an 
##                            extension on 'lib' to indicate 32 bit.  e.g. 
##                            IRIX defines /usr/lib32
##              for ARCH=64 - Always define ARCHINST.  Even if the OS 
##                            doesn't make a distinction, we will.
