00101  *
00102  * These functions probably were originally intended for internal use only.
00103  * However, due to
00104  *   - the lack of good documentation
00105  *   - this being the obvious way to save a file
00106  *   - the fact that libgphoto2 has been exporting all its internal
00107  *     symbols for years (until 2005-06)
00108  *   - our in-house frontends gphoto2 and gtkam using them
00109  * a number of external frontends started to use these functions, as
00110  * of 2005-06:
00111  *    - digikam
00112  *    - f-spot
00113  *    - gthumb
00114  * But a few frontends can live without it (and thus are likely to
00115  * use the correct API):
00116  *    - flphoto
00117  *    - kamera
00118  *
00119  * So we're going to phase these functions out over the next year or
00120  * so, going the GTK way of keeping the ABI but breaking the API. So
00121  * we'll continue to export functionally equivalent functions, but the
00122  * header files will not contain definitions for you to use any more.
