mimExplode - mime multipart exploder v0.1
    =========================================

    requires:
    
        bash
        cut
        echo
        grep
        head
        sed
        
    usage:
    
        ./mimExplode.sh inputFile outputPrefix
        
        - inputFile 
            raw SMTP dump, e.g. a mail file from .maildir folders
            
        - outputPrefix
            if a directory exists, the parts will be put there,
            otherwise the parts will be saved with this prefix
            (internally needed for recursion)
            
    example:
    
        run ./example.sh, it will create a folder and put there the
        parts of the sample.SMTP
        
    internal configuration:
    
        there are two pairs of options which controls how deeply we
        parse the files and how much garbage we leave behind
        
        default settings: total explosion with no garbage/temporary files
        
    output:
    
        MULTIPART
            (always)
            root     - header of the multipart message
            fragment - part of a multipart message
        
        TRANSPORT ENCODING 
            (affected by decode_base64, remove_decoded)
            decoded  - file which was BASE64 decoded (after decoding)
            base64   - file which was BASE64 decoded (before decoding)
            
        RECURSION 
            (affected by explode_recursive, remove_exploded options)
            exploded - file which was recursively exploded
