# Description:

#

# This script changes a JRT version to a binary version usable as 

# Symbian mmp-file version or qmake's version.

# - each version part is cut to three digits, and then to 8 bits

# - qmake's version is taken as is, mmp's version is mangled as by qmake (the

#   resulting version is the same in binaries).

# - major version is always 10
