-// This file is only used for testing the preparser.
-// The first argument must be the path of a JavaScript source file, or
-// the flags "-e" and the next argument is then the source of a JavaScript
-// program.
-// Optionally this can be followed by the word "throws" (case sensitive),
-// which signals that the parsing is expected to throw - the default is
-// to expect the parsing to not throw.
-// The command line can further be followed by a message text (the
-// *type* of the exception to throw), and even more optionally, the
-// start and end position reported with the exception.
-//
-// This source file is preparsed and tested against the expectations, and if
-// successful, the resulting preparser data is written to stdout.
-// Diagnostic output is output on stderr.
-// The source file must contain only ASCII characters (UTF-8 isn't supported).
-// The file is read into memory, so it should have a reasonable size.
-
-
-// Adapts an ASCII string to the UnicodeInputStream interface.
