base62 encode decode utility

We have hosted the application base62 encode decode utility in order to run this application in our online workstations with Wine or directly.

Quick description about base62 encode decode utility:

the package chewingum contains two main programs:
- base62
- chew
They have been implemented in perl.
Base62 has been coded in c++ too.

chew has been written to shorten long decimal integer numbers into base62 strings.
It's not a mere base conversion, because it doesn't use arithmetic inside its logic.
In this way it can convert very long numbers into strings quickly,
without overflows.
For example if I want to share an id using an url, this will make the url shorter.

the base62 program has been written to encode/decode files
into this format.
The syntax is similar to the popular base64 command line program.

Inside the package there is a working c++ version of the base62 algorithm.

the sources are inside the package.

Note that from release 2.0.0 the algorithm is a little different from the one
used before.
So if you have coded a file using base62 < 2.0.0 DO NOT USE base62 >= 2.0.0 to decode it
