-/* Reading "files".  The contents of some files are written into kdb's
-   data area before it is run.  These files are used to contain the
-   symbol table for kdb to load, and the source files (in case the
-   kdb user wants to print them).  The symbols are stored in a file
-   named "kdb-symbols" in a.out format (except that all the text and
-   data have been stripped to save room).
-
-   The files are stored in the following format:
-   int     number of bytes of data for this file, including these four.
-   char[]  name of the file, ending with a null.
-   padding to multiple of 4 boundary.
-   char[]  file contents.  The length can be deduced from what was
-           specified before.  There is no terminating null here.
-
-   If the int at the front is zero, it means there are no more files.
-
-   Opening a file in kdb returns a nonzero value to indicate success,
-   but the value does not matter.  Only one file can be open, and only
-   for reading.  All the primitives for input from the file know
-   which file is open and ignore what is specified for the descriptor
-   or for the stdio stream.
-
-   Input with fgetc can be done either on the file that is open
-   or on stdin (which reads from the terminal through tty_input ()  */
