This is how I figured out the signing process 'till now 
(fixed width font)!!
{<utility>}
file

                        file (raw)
                            |
                       {fillapp} - Adds :020000020000FC\n on top of the file
                            |
               -------<----------->-------
               |                         |
        {rabsig 0104.key} - Makes        |
               |          signature,     |
               |      file is unmodified |
               |                         |
       signature (binary)                |
               |                         |
        {0x02,0x2D added to top of       |
         signature}                      |
              |                          |
        {convert} - makes signature hex  |
              |                          |
       signature (Intel Hex format)      |
              |                          |
              |                          |
              ---------->-----<-----------
                           |
                     {addHex} - Adds Hex signature after file, 
                           |    but preserves intel hex style.
                           |    **See explanation**
                           |
                        *.app file
                           |
                     {GlHeader} - makes 8xk file
                           |
                        *.8xk file

**Explanation by addhex*

:05000000 0504060000 EA
:00000001 FF

joined with

:05000000 0302000005 F0
:00000001 FF

gives

:10000000 05040600000303000005 DB
:00000001 FF
