//-------------------------------------------------------
// This program generates .spr sprite package files.
// The format of the files is as follows:
//
// dsprite_t file header structure
// <repeat dsprite_t.numframes times>
// <if spritegroup, repeat dspritegroup_t.numframes times>
// dspriteframe_t frame header structure
// sprite bitmap
// <else (single sprite frame)>
// dspriteframe_t frame header structure
// sprite bitmap
// <endrepeat>
