Function:	File Format Identification

Description

It is designed to be minimalistic and inherently cross platform compatible. It is also designed to be a stand in for python-magic, it incorporates the functions from_file(filename[, mime]) and from_string(string[, mime]) however the magic_file() and magic_string() are more powerful and will also display confidence and duplicate matches.

It does NOT try to match files off non-magic string. In other words it will not search for a string within a certain window of bytes like others might.

Advantages over using a wrapper for 'file' or 'libmagic':

• Faster
• Lightweight
• Cross platform compatible
• No dependencies

Disadvantages:

• Does not have as many file types. ("Only" 1600 at the time of posting)
• No multilingual comments
• Duplications due to small or reused magic numbers
