 /* Maximum size of the dynamic table.  The maximum number of code structures is
    1444, which is the sum of 852 for literal/length codes and 592 for distance
    codes.  These values were found by exhaustive searches using the program
-   examples/enough.c found in the zlib distribtution.  The arguments to that
+   examples/enough.c found in the zlib distribution.  The arguments to that
    program are the number of symbols, the initial root table size, and the
    maximum bit length of a code.  "enough 286 9 15" for literal/length codes
    returns returns 852, and "enough 30 6 15" for distance codes returns 592.
