/* xjt.c
 *
 * XJT (JPEG-TAR fileformat) loading and saving file filter for the GIMP
 *  -hof (Wolfgang Hofer)
 *
 * This filter requires UNIX tar and the "jpeglib" Library to run.
 * For optional further compression you also should install
 *  gzip and bzip2 compression Programs.
 *
 * IMPORTANT NOTE:
 *   This plugin needs GIMP 1.1.18 or newer versions of the GIMP-core to run.

 * version 1.3.14a; 2003/06/03  hof: bugfix: using setlocale independent float conversion procedures
 *                                   p_my_ascii_strtod (g_ascii_strtod()) and g_ascii_formatd()
 * version 1.1.18a; 2000/03/07  hof: tattoo_state
 * version 1.1.16a; 2000/02/04  hof: load paths continued, load tattos, load/save unit
 * version 1.1.15b; 2000/01/28  hof: save/load paths  (load is not activated PDB-bug)
 *                                   continued save/load parasites,
 *                                   replaced static buffers by dynamic allocated memory (goodbye to sprintf)
 * version 1.1.15a; 2000/01/23  hof: NLS_macros, save/load parasites, \" and \n characters in names
 *                                   use G_DIR_SEPARATOR (but you still need UNIX tar to run this plugin)
 *                                   older gimp releases (prior to 1.1.15) are not supported any more.
 * version 1.02.00; 1999/03/16  hof: - save layer/channel Tattoos
 *                                   - load/save image resolution added
 *                                   - tolerate unknown properties with warnings
 * version 1.01.00; 1998/11/22  hof: added load/save of guides
 *                                   (you need gimp 1.1 to use this feature)
 * version 1.00.00; 1998/10/29  hof: 1.st (pre) release
