bump_version.py

C++的一个好库。。。现在很流行

#!/usr/bin/python

# This script is used to bump version of bjam. It takes a single argument, e.g
#
#    ./bump_version.py 3.1.9
#
# and updates all necessary files. For the time being, it's assumes presense
# of 'perl' executable and Debian-specific 'dch' executable.
