# generate vcxproj file(s)
#
# howto:
#   scons --clean
#   scons <a_target> > out
#   python buildscripts/make_vcxproj.py < out > out1 && cat buildscripts/vcxproj.header out1 > a_target.vcxproj
#
# note: the vcxproj.header file currently references "mongod.exe" explicitly rather than being generic.
#       this will be changed soon but gets us started.  
#       also, directory paths are such that it is assumed the vcxproj is in the top level project directory.
#       this is easy and likely to change...
