# Dealing with Visual Studio MANIFESTS
#=====================================

# Functions to deal with visual studio manifests. Manifest are a mechanism to
# enforce strong DLL versioning on windows, and has nothing to do with
# distutils MANIFEST. manifests are XML files with version info, and used by
# the OS loader; they are necessary when linking against a DLL not in the
# system path; in particular, official python 2.6 binary is built against the
# MS runtime 9 (the one from VS 2008), which is not available on most windows
# systems; python 2.6 installer does install it in the Win SxS (Side by side)
# directory, but this requires the manifest for this to work. This is a big
# mess, thanks MS for a wonderful system.

# XXX: ideally, we should use exactly the same version as used by python. I
# submitted a patch to get this version, but it was only included for python
# 2.6.1 and above. So for versions below, we use a "best guess".
