+// This is meant to be a small and dumb interpreter for wast files. Either it
+// is imported by another script, which needs to define an array of arguments
+// called importedArgs, or args need to be passed to the command line.
+//
+// Possible arguments include:
+// -d enable debug verbose mode
+// -c computes line numbers in wast files (disabled by default as it
+// slows down the parser a lot)
+// -s soft fail mode: if a test fails, don't abort but continue to
+// the next one.
+// * anything else is considered a relative path to the wast file to
+// load and run. The path is relative to to the runner script,
+// i.e. this file..
+//
+// If there are no arguments, the wast interpreter will run sanity checks
+// (testing that NaN payload comparisons works, e.g.).
