// spritegn.h: header file for sprite generation program

//-------------------------------------------------------
// 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>
