This class can be used to compress and uncompress data using the variable length encoding.

It can read a stream of data and pack it using an pure PHP implementation of the variable length encoding algorithm.

Variable length coding is a compression algorithm that is not very efficient for compressing arbitrary data.

However, it can be very efficient for compressing data with long sequences of repeated data.

This class provides an PHP implementation of the variable length coding algorithm. It can be useful when the data to compress is conveniently arranged.

Since it is a pure PHP based implementation, it may also be useful when the special PHP extensions that implement more efficient algorithms are not available.
