136 *
137 * These functions probably were originally intended for internal use only.
138 * However, due to
139 * - the lack of good documentation
140 * - this being the obvious way to save a file
141 * - the fact that libgphoto2 has been exporting all its internal
142 * symbols for years (until 2005-06)
143 * - our in-house frontends gphoto2 and gtkam using them
144 * a number of external frontends started to use these functions, as
145 * of 2005-06:
146 * - digikam
147 * - f-spot
148 * - gthumb
149 * But a few frontends can live without it (and thus are likely to
150 * use the correct API):
151 * - flphoto
152 * - kamera
153 *
154 * So we're going to phase these functions out over the next year or
155 * so, going the GTK way of keeping the ABI but breaking the API. So
156 * we'll continue to export functionally equivalent functions, but the
157 * header files will not contain definitions for you to use any more.
