title: Linux file utility magic.mgc database get content
body: <p>I write project where I need to identify certain file formats.
  For some formats I have found signatures that I use for identifying easily (mp3, ogg), with another formats  I have a big problem (like MPEG ADTS) - I just cannot find what kind of signature can be used for it. </p>
  
  <p>I found out that File  utility for Linux environment can do it. 
  I tried to search it in source code, but I've found nothing.</p>
  
  <p>I found that file utility holds its database in magic.mgc file. But it's hold in binary form.
  It looks like:

  <p>Does someone perhaps know how to find that database in plain text format?</p>
