:: Notes about batch files for Python people:
::
:: Quotes in values are literally part of the values:
:: SET FOO="bar"
:: FOO is now five characters long: " b a r "
:: If you don't want quotes, don't include them on the right-hand side.
::
:: The CALL lines at the end of this file look redundant, but if you move them
:: outside of the IF clauses, they do not run properly in the SET_SDK_64==Y
:: case, I don't know why.
