Compressing text files via telegram bot.

compression package contains a clear implementation of the arithmetic compression algorithm.
The high idea is to encode the entire message into a single number in range 0 <= p <= 1. The efficiency of the algorithm on random Russian novels is about 35-40%. Read more here.

Feel free to use scripts to compress or decompress your files from the command line.

Example:

`compress.py InFile [, otherFiles]`

`decompress.py CompressedFile`

You can also use telegram bot, which has some other useful features such as compressing all text files found on a given web-page. Start a dialog with @arithmetic_compressor_bot and follow further instructions.
