# binary-type

A simple package that provides the ability to check if a buffer matches

a specific mimetype, and secondly the ability to guess a mimetype given

a buffer.

## Reference

### `matches(mimetype, buffer) => Boolean`

Return true if the supplied `buffer` has a binary file signature that

matches what is expected for the specified `mimetype`.

### `guess(buffer) => String`

Run the supplied `buffer` through the various known mimetypes to attempt

to determine it's mimetype (returned as a string value if found).

__NOTE:__ Only a few file signatures have been implemented at this stage,

but feel free to issue a pull request if you require additional types. A

good resource of binary file signatures can be found at the following url:
