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