  31 // This program generates .spr sprite package files.

  34 // dsprite_t file header structure
  35 // <repeat dsprite_t.numframes times>
  36 //   <if spritegroup, repeat dspritegroup_t.numframes times>
  37 //     dspriteframe_t frame header structure
  38 //     sprite bitmap
  39 //   <else (single sprite frame)>
  40 //     dspriteframe_t frame header structure
