Some suggestions for the subfiles:

17:35 CoCoALib Support #1161 (Closed): Split NumTheory.C into several smaller files

The file *@NumTheory.C@* has become rather large. Consider splitting it into several smaller files.

17:33 CoCoALib Support #1160 (New): Clean up revised RatReconstructByContFrac code

The @RatReconstructByContFrac@ code has been revised (made better?), but there is lots of commented out cruft.

Some notes John Abbott

12:37 CoCoALib Design #1156: Printing for RingElem

Part of the motivation is that it seems to be tricky to resolve issue #930 about printing out TwinFloat values as pol... John Abbott

12:30 CoCoALib Design #1156 (New): Printing for RingElem

JAA would like to reconsider the design of printing for @RingElem@ because the current design is rather inelegant. John Abbott

Ideas John Abbott

12:28 CoCoA-5 Bug #1152: Release: problems with sed

*(A)* The simplest solution is to call @sed@ directly without using its full path:
* *@+++@* should work everywhere

20:49 CoCoALib Feature #1154 (Closed): SmallFpImpl: new ctor arg to say do-not-check-that-arg-is-prime

I propose adding a new ctor for @SmallFpImpl@ where the caller can use a flag to guarantee that the arg is prime.

15:28 CoCoA-5 Feature #368: port SmithNormalForm (CoCoA-4)package to CoCoA-5

This should be ported to CoCoALib (once it has been corrected). It would surely be faster ;-)

CoCoA-5 has both *@ConcatList@* and *@ConcatLists@*. They are identical.
