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