14:29 Support #1548 (New): Man page for UniversalGBasis
- The manual page for @UniversalGBasis@ could be clearer.
Improve it!

- I have had a (not so) quick look at the code involved.
*@describe@* like all CoCoA commands returns no value, and th...

sadly CoCoA does not offer a (nice) way to save objects (rings, polys, lists,...) in such a way that they can be... -

This happens (at least) ... -
- Now CoCoAInterpreter look for packages (if not specified) in its own directory. Add also the path "../"
-
- I've done it for *@defaultPackageDir@* which is now *@IsDefaultPackageDir@*.
I find it easier, and that's the reason... -
- Should we (slowly?) adapt parser/interpreter/main to our coding conventions?

- I now have a personal CoCoA version with the new @MemPool@ code (see issue #1522 comment 10).
I have just tried the ...

- Anna will impl in CoCoAlib, and then make accessible to CoCoA-5.

- Very good reasoning.
Indeed some researchers have opposite standards, calling lex (and degrevlex) what we call xel (... -

It compiles and the CoCoA-5 tests all pass.

For that application, it wou... -

- What was nice was that Bernhard wrote "shouldn't cocoa-5.2 be cocoa-5.2?"
So even bug reporters can make typos ;-)
-
- Done.
I added "Boost" only in BuiltinFunctions.C.
I have also the code for adding it in ExternalLibs.C (commented o...
