files easier. Examples:
substitute inputFile outputFile \
--replace "@bindir@" "$out/bin" \
--replace "@gcc@" "$GCC/bin/gcc"
substitute inputFile outputFile --subst-var out
(this is sugar for --replace "@out@" "$out")
substituteInPlace file --replace a b
(input and output are both `file'; the execute bit is preserved)
