+TODO List for PEL
+*****************
+
+In addition to the following list, then the source contains a number
+of comments beginning with `TODO' and `FIXME' which marks extra places
+where attention is needed.
+
+The list has been roughly ordered by priority and the release
+targeted.
+
+
+PEL Version 1.0
+---------------
+
+* Add convenience functions.
+   It would be nice to have functions that could give you a particular
+   entry or the embedded thumbnail with just one function call.
+   Manually traversing the directory structure (and repeatedly
+   checking for null pointers) requires too big a knowledge of the
+   structure of JPEG, TIFF, and Exif formats.
+
+
+PEL Version 1.x
+---------------
+
+* Only load necessary data.
+   SF #1210126: instead of parsing the entire JPEG/TIFF image, we
+   should load data as necessary.  This will save memory with big
+   images.
+
+* Interpret the MakerNotes.
+   The libexif project already has code for interpretating the
+   MakerNotes for a number of different camera models.
+
+* Handle character encodings of the USER_COMMENT tag.
+   The first eight bytes store the character encoding, but PEL ignores
+   them for now.  Using the Multibyte String PHP extension we should
+   be able to convert the data.
+
+* Deal with characters outside Latin-1 in PelEntryWindowsString.
+   This needs testing from people running Windows XP set to a locale
+   different from Latin-1.
+
+
+PEL Version 2.0
+---------------
+
+* Restructure information about tags.
+   Currently information about the tags are stored in several places
+   around the code, making updates difficult.  All information about a
+   tag should be stored at one place, maybe by having a class per tag
+   (how well does PHP handle 142 small classes?).
+
+   The information in question is:
+
+   - hex code,
+   - title,
+   - name,
+   - description
+   - format,
+   - components,
+   - valid IFD types,
+   - how to load data,
+   - how to display (the getText() method)
+
+   This will most likely break API compatability and is delayed for
+   PEL 2.
