Shellheader

Generates a header for popular calculator shells.

The directive generates code (and inserts it at the current point) according to the list.

/*Ion*/
  ret
  jr nc,Start
  .byte "Description",0
Start:
/*MirageOS*/
  ret
  .byte 1
  ; 30 bytes for 15x15 icon.
  .byte "Description",0
/*Venus*/
  .byte $E7,$39,$5F,$5B,$56,$3F,$00
  jr nc,Start
  .byte "Description",0
  ; If specified, 32 bytes for 16x16 icon.
Start:

You still need to specify the start origin yourself. You will also need to manually add the AsmPrgm header for TI-83 Plus programs.
The directive will report a warning if there is not two bytes output before this directive (TI-83 Plus) or if data is output before this directive at all (TI-83).
