 # Build system for nissy, run './build help' for info on how to use this.
 
 # The variables below can be used to personalize the build system. For example,
 # to compile with clang instead of the default cc one can use:
 #
 #   CC=clang ./build
 # 
 # Each variable also has a counterpart that starts with NISSY_BUILD_*. These
 # other variables can be set, for example, in your shell configuration file
 # to change the default build options. They are still overwritten by the values
 # of the non-NISSY_BUILD_* variables, if set.
 # For example, on a system that supports the addressed and undefined behavior
 # sanitizers, one can set
 #
 #   export NISSY_BUILD_SANITIZE="address,undefined"
 #
 # so that these sanitizers will be enabled when building nissy in debug mode.
 # If later the same user wants to build a debug version without sanitizers,
 # they may use
 #
 #   SANITIZE="" ./build debug
 #
 # And the empty string value will take precedence.
