To build the module run:

    node-waf configure build

This will produce `base62.node` binary module. To use it, make sure the
module's directory is in NODE_PATH.

The module exports two functions `encode`, and `decode`.

encode
------

Encodes an integer to base62.

Here is a basic example:

    var sys = require('sys');
    var b62 = require('base62);

    sys.print(b62.encode(123456789));

    /* Output: 8m0Kx */

decode
------

Decodes a string to the original integer encoded by encode function.

    var sys = require('sys');
    var b62 = require('base62');

    sys.print(b62.decode('8m0Kx'));

    /* Output: 123456789 */
