# Times script using Visual Studio compiler in Windows
#
# This script assumes that you have:
# Python 3
# Visual Studio (script assumes VS2013, manipulate the sed command otherwise)

# Command line svn. TortoiseSVN with that feature selected works.
#
# Usage:
# Open VS command prompt.
# cd c:\users\...
# svn checkout https://github.com/danmar/cppcheck/trunk cppcheck-svn
# cd cppcheck-svn
