+Here are some things left to do.  If you would like to contribute, send
+mail to me (olaf@infovore.xs4all.nl) first.
+
+* Use binary mode for all files (but do obey end-of-line conventions for
+  the specific platforms.
+
+* Give TeX more options: 
+  output filename:lineno: msg on error
+  change prompt from `\n*' (for simpler cut-and-paste)
+
+* Have bibtex -verbose print full pathnames.
+
+* Make TeX--XeT a configure-time or runtime option?
+
+* Deal with the configure tests that prevent cross-compilation:
+  - Remove use of schar (in dvicopy, mf, pktogf, and tangle).
+  - Learn endianness at runtime, include both Big and LittleEndian
+    versions in code, call appropriate one.
+  - Figure out what to do about the sizeof long test.
+
+* Reallocate memory arrays as needed instead of just allocating once at
+  the beginning.
+
+* Possibly use spiff when doing the triptrap comparisons, so acceptable
+  differences can be eliminated.
+  
+* Make web2c handle fields correctly, i.e., to put the field identifier
+  in the symbol table of the type, instead of the global symbol table. 
+  This would simplify the GFtoDVI change file a fair amount.
+
+* Make web2c handle variant records.  This would make the TeX, Metafont,
+  and GFtoDVI change files all simpler.
+
+* Implement overflow checking for adding and subtracting dimensions.
+  According to Knuth "a few dozen checks" would be needed (section 104).
+  Knuth calls the chances of it occuring unlikely, but unfortunately you
+  will get a bad DVI file when it does.  The following source demonstrates
+  the problem.
