       readfile - return the entire contents of a file as a string

       @load "readfile"

       result = readfile("/some/path")

       The  readfile  extension	 adds a single function named readfile().  The
       argument is the name of the file to read.  The return value is a string
       containing the entire contents of the requested file.

       Upon error, the function returns the empty string and sets ERRNO.

       @load "readfile"
       contents = readfile("/path/to/file");
       if (contents == "" && ERRNO != "") {
	   print("problem reading file", ERRNO) > "/dev/stderr"
