+// known bugs; there may be others!! chris elliott, biol75@york.ac.uk 27 Mar 01
+
+// 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 n??ever will

//
// For both formats spaces are ignored and lines starting with a '#' are

// a) for "brief" format:
// <mime type> <space separated list of extensions>
// b) for "expanded" format:

// We try to autodetect the format of mime.types: if a non-comment line starts
// with "type=" we assume the second format, otherwise the first one.
// there may be more than one entry for one and the same mime type, to
// choose the right one we have to run the command specified in the test
// field on our data.
