+
+// 1) .mailcap and .mimetypes can be either in a netscape or metamail format
+//    and entries may get confused during writing (I've tried to fix this; please let me know
+//    any files that fail)
+// 2) KDE and Gnome do not yet fully support international read/write
+// 3) Gnome key lines like open.latex."LaTeX this file"=latex %f will have odd results
+// 4) writing to files comments out the existing data; I hope this avoids losing
+//    any data which we could not read, and data which we did not store like test=
+// 5) results from reading files with multiple entries (especially matches with type/* )
+//    may (or may not) work for getXXX commands
+// 6) Loading the png icons in Gnome doesn't work for me...
+// 7) In Gnome, if keys.mime exists but keys.users does not, there is
+//    an error message in debug mode, but the file is still written OK
+// 8) Deleting entries is only allowed from the user file; sytem wide entries
+//    will be preserved during unassociate
+// 9) KDE does not yet handle multiple actions; Netscape mode never will
+
+// TODO: this file is a mess, we need to split it and review everything (VZ)
