# The question how v1 and v1.0 relate to each other is not a trivial one.
#
# For instance, Python considers v1 == v1.0:
# $ test.py
# #!/usr/bin/python3
# from packaging.version import parse
# v1_0 = parse("1.0")
# v1 = parse("1")
# print (v1 == v1_0)
# $ ./test.py
# True
#
# OTOH, version sort from coreutils considers v1 < v1.0:
# $ cat bla.txt
# 1.0
# 1
# $ sort -V bla.txt
# 1
# 1.0
#
# Proc version_compare seems to have taken the latter approach.
