# The first version found in the list is the one used by default if
# there are multiple versions installed.  Barring good reasons to
# the contrary, this means we should list versions from most recent
# to oldest.  Pro versions get listed before Express versions on the
# assumption that, by default, you'd rather use the version you paid
# good money for in preference to whatever Microsoft makes available
# for free.
#
# If you update this list, update _VCVER and _VCVER_TO_PRODUCT_DIR in
# Tool/MSCommon/vc.py, and the MSVC_VERSION documentation in Tool/msvc.xml.
